As it has already been pointed out. The reference material on the IFI site is priceless when designing any custom electronics for a robot, weither it is robot side or operator side.

Basicly what you do is take all of your switches and pots, and other sensors if you so choose, and wire them up into the OI through the ports that are normaly used for joysticks.

Each joystick port has several analog and digital inputs, as well as LED outputs. Some of the inputs are shared between the joysticks so make sure you check out the OI reference guide.

Look through the image galleries from the last couple of years and i'm sure you can find some pictures of peoples controls.

Hope this helps...If you have any more questions feel free to ask.
