I did that with my Logitech gamepad: the joysticks do gradual motion and
the buttons do on-off motion.

This should get you started:

I wrote up a somewhat more elaborate version  for Digital Machinist
magazine. You can fetch the files (but not the article itself) from:

http://www.digitalmachinist.net/files/downloads/2010Winter/DM%205.4%
20Nisley.zip

There's a bit of trickery in that version to avoid some race conditions,
but the overall logic is straightforward.

As soon as I got it set up, there was no going back!

Look at the mux4 component. define states 00 and 11 to be 0 output, 01
to be +speed and 10 to be -speed. Then link the buttons to the sel0
and sel1 pins: http://www.linuxcnc.org/docview/html/man/man9/mux4.9.html
