Since the JPanel is the underlying container in your proposed design you could
very easily use JButton as the component for your "control" buttons. If you
need the button to look like something other than the standard JButton, simply
create some gif images as button faces.
Adding the buttons to your JPanel is as uncomplicated as using a layout manager
that places the buttons where you need them, and then let Java do the painting.
Naturally, if you need custom MouseListeners, you'll have to write those, but
they're easily attached to the button controls you need.
This is not just theory as I have had good success doing precisely what you
want to do using the methods I've just described.
