You are constructing your GUI after the frame is made visible, and never re-validating it (and another nono is you are doing it outside the event dispatch thread but that is minor).

Reorder the code so the JPanel is made and added to the Frame before the frame.setVisible() method is called. You should also set the size of the Frame before making it visible.

Call frame.pack(). It will set the size automatically to its preferred size. And also move the setVisible(true) call to the end as Steve suggested.
