Several years ago I wrote a VB application to control the robovation (mini RC) controller from a PC using a serial cable on the program port. I don't know if the latency of the wifi adapters would affect it, but you can give it a shot. The code should port to the full size robot controller, but if you have a mini-rc you can use it without making any modifications. When you run setup it will add help.txt to the installation folder with basic information about how to get it working. The joysticks don't automatically re-center when you release them, but right-clicking will do it.
