I hope this helps . As an alternative, you could use an ArrayList. It is a resizable-array implementation of the List interface.
Usage (using String):

Hope that helps I saw another way in one of the examples in a book called "C++ GUI Programming with Qt 4". They did it with
code :
    setFixedHeight(sizeHint().height());

wish helps you Take a look at JSplitPane and the corresponding Java Tutorial. This component can do exactly what you want and it behaves very well. Try the first example in the tutorial, you'll see.

To fix the issue you can do There is a simple fix that works almost all the time: make your frame not resizable after having set visible. So only modifies your code this way:
code :
public static void main(String[] args) {

    Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();

    JFrame frame = new JFrame("Jedia");
    frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
    frame.setSize(screenSize);
    frame.setVisible(true);    // FIRST visible = true
    frame.setResizable(false); // THEN  resizable = false
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

I hope this helps . Maybe a BoxLayout will work. Box layout will respect the minimum size of a component. See the section from the Swing tutorial on How to Use Box Layout for more information.

I think the issue was by ths following , You need some layout to place your widgets and you need set alignment also.I edited your code bit to get what you looking for. And I edited the close event also.
from PyQt4 import QtCore, QtGui import sys
code :
# Encoding Utf-8*
try:
    _from_utf8 = QtCore.QString.fromUtf8
except AttributeError:
    def _from_utf8(s):
        return s
try:
    _encoding = QtGui.QApplication.UnicodeUTF8

    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig)

# Main Window


class Window (QtGui.QMainWindow):
    def __init__(self):
        super(Window, self).__init__()

        self.setGeometry(100, 100, 800, 600)
        self.setWindowTitle(_from_utf8("Virtual Library"))
        self.setStyleSheet("background-image: url(nwlib.jpg);")

        # ExitOption
        menu_action1 = QtGui.QAction("Exit", self)
        menu_action1.setShortcut("Ctrl+Q")
        menu_action1.setStatusTip('Exit The App')
        menu_action1.triggered.connect(self.close_application)

        self.statusBar()

        # MenuBar
        main_menu = self.menuBar()
        file_menu = main_menu.addMenu('Options')
        file_menu.addAction(menu_action1)

        self.home()

    def home(self):

        # NewLibrary btn
        centralwidget = QtGui.QWidget(self)
        self.mainLayout = QtGui.QVBoxLayout(centralwidget)
        new_lib_btn = QtGui.QPushButton("New Library", self)
        new_lib_btn.setMinimumSize(141, 41)

        # AccessLibrary btn
        access_lib_btn = QtGui.QPushButton("Access Library", self)
        access_lib_btn.setMinimumSize(141, 41)

        # FindNewBooks btn
        find_nbooks = QtGui.QPushButton("Find New Books", self)
        find_nbooks.setMinimumSize(141, 41)

        self.mainLayout.addWidget(new_lib_btn)
        self.mainLayout.addWidget(access_lib_btn)
        self.mainLayout.addWidget(find_nbooks)

        self.mainLayout.setAlignment(QtCore.Qt.AlignCenter)

        self.setCentralWidget(centralwidget)

        self.show()

    def close_application(self):
        choice = QtGui.QMessageBox.question(self, 'Exit',
                                        "Close the application?",
                                        QtGui.QMessageBox.Yes | QtGui.QMessageBox.No)
        if choice == QtGui.QMessageBox.Yes:
            sys.exit()
        else:
            pass


def run():
    app = QtGui.QApplication(sys.argv)
    GUI = Window()
    sys.exit(app.exec_())


run()
