One of the cheapest, easiest to hack pieces of hardware out there is a 
keyboard. Either the old serial ones (mini din) or the USB type already 
have 100 plus switches worked out. It is recognized by linux and X and so 
by any app, most of which have key mappings already. So long as you are 
using less than the full number of switches, it is pretty easy to select 
switch points where there can be multiple key presses at once. A pot is a 
bit harder (and there is midi pots out there) but could be done with two 
switches where moving the pot one way selects one switch and moving it the 
other way selects the other.

Keyboards (if you just can't find them free... a coffee spill is not a 
problem) can be had for $3 each at thrift stores or even the dollar store 
brand new.
