Got a simple app that's a frame and a jpanel with buttons on it.
Can't work out how to close it using one of the buttons rather than the
graphical interface provided.

Calling the dispose method of the JFrame object should do it.

Buttons are part of the GUI. Are you asking?

1. how do I close the frame gracefully and exit if my program decides
it would be a good idea?

2. what kind of code to I put in the event listener for the button to
close the frame and shut down.

See http://mindprod.com/jgloss/frame.html
http://mindprod.com/jgloss/jframe.html

The key is the Frame/JFrame.dispose method.

See also System.exit( int );
