First off, don't unnecessarily mix AWT and Swing components in the same GUI -- as implied by your import of java.awt.Button.

Second, reduce code to the minimum when asking for free help on a forum,. That means getting rid of all unused imports, unused implementations and empty methods, and multiple blank lines.

Third, set the top level window visible only after all components have been added.

Moving this thread from New to Java to the appropriate section.
