These are called "spinners". I had one of these, but no longer have
access to the source code (and a quick Google search didn't turn up
anything). They are not too hard to make, I just displayed the images
of up and down arrows in resource/bitmaps in a draw widget and handled
the events. For extra credit, make the button press 3D and have an
acceleration effect when the button is held down.
