how can I make this H shifter?

I seen this instructable and I found it cool so I decided to make one.
I decided, based in other instructables using a cheap pc USB game controller. I have seen how to make the steering wheel, and I decided to make the pedals with linear potenciometers, such as the parking brake, but I don't know how to make the H shifter. Can somebody help me?

you don't need a separate button just 1 for up and 1 for down. It is only the out side that looks likE an H SHIFT.

If you really want the H shift to work properly your going to need to use a microprocessor to detect if your shifting up or down and produce the relevant signals.
Have the shifter hit a switch at the end of each point in the H.

I already thiked about that, but what game controller has a button for each gear?
None thats why its a custom build. Most games allow you to shift up and daown right? Well each button doesn't have to be for a specific gear. You make a Macro for each button so the upper ones will shift up. The bottom left shifts down and the bottom right of the H gives you reverse.
