encoder with a digital potentiometer so you could use a standard gameport.
I didn't get very far but you may want to look at these to links for digital
potentiometers to connect to a load cell for a pressure sensitive brake
pedal. If you get this working I would be very interested in doing it also.

IMO if someone wanted to build their own FF steering wheel, the best
approach would be to buy a production unit (I've seen some units at $69 US)
and retofit the mechanics to your wheel. Building the circuit, developing
software to control it and then writting a Windows game controller driver
would just be too much to do.
