David,

You can use a glasspane to set the wait cursor and 
intercept events.

For example:

    private class GlassPane extends JComponent 
    {
        public GlassPane() 
        {
            addKeyListener(new KeyAdapter() { });
            addMouseListener(new MouseAdapter() { });
            super.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
        }
     }                            


In the constructor of the dialog do:

     setGlassPane(new GlassPane()); 



When you want to disable the dialog:

dialog.getGlassPane().setVisible(true);

Then to re-enable it:

dialog.getGlassPane().setVisible(false);
