Making Custom Hardware

Ok /prog/

I want to build my own hardware for my computer but have no clue where to start.  My design will be simple game controller with 6 buttons (up, down, left, right, A, start).  I would LIKE a usb connection, but a serial port or parallel seems more simple.

I also need to program it.  What would be the best method for making custom drivers?

Are there any good tutorials for making simple hardware like this? (I'm running window XP)

You still don't know Ohm's Law, the basic thing everyone related to electricity should know. God fucking damn. Why, I ask you, why? It's like the most basic thing ever.
