GHI makes an Arduino compatible board with an Arm 7 on it. You program it with dot net C#. It has a USB host interface and a Class that will allow you to pull the values from a wireless USB game controller eliminating the PC.

I like the Pololu servo driver boards

Plug the usb wireless into the arm board and then talk to the servo board by serial. Gives rock solid control. Assuming one has C# experience.
