I believe this part:

private JMenuBar createMenuBar()
{
JMenuBar menuBar = new JMenuBar();
JMenu menu;
JMenuItem item;

item = new JMenuItem("Exit");
item.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent evt)
{
System.exit(0);
}
});

return menuBar;
}

Should be like this:

private JMenuBar createMenuBar()
{
JMenuBar menuBar = new JMenuBar();
JMenu menu;
JMenuItem item;
menu.add(item);
menuBar.add(menu);


item = new JMenuItem("Exit");
item.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent evt)
{
System.exit(0);
}
});

return menuBar;
}
