If you do choose to go with the GPIO route, unless your code for
accessing the GPIO lines does debouncing, you will have to debounce the
key.  There are lots of examples out there (most in C on the arduino,
but still applicable). Most of them check for a button press, then do a
timer count-down to let things settle out before recording a button
press.  So it's still complicated even if you talk directly to the
buttons!  No way around some complexity though.
