Hey, I told you guys I would do it. I am a tiny bit late however with uploading this. Hope you don’t mind! 
I used the C# library WiiMoteLib to get the wiimote inputs, and I translated those inputs to a (X,Y) coordinate which is used to calculate the angles of each of the joints. The D-Pad controls the Y coordinate and rotation of the base, and the tilt of the wiimote controls the X coordinate.
If I find time later on, I will attach this arm to a 4WD rover kit, and use the Nunchuck wiimote addon to control the wheels.
I had a lot of fun working on this in my spare time.
