Creating buttons that event handle with a visual c++ program

I will try to explain this the best that I can. I currently have a program that at the moment just cycles through menus by clicking some button graphics that I have created. I am also using CE emulator to have an emulation of what the program will be on. I have created a skin for the device and added buttons (see xml below) that make an indication when they are pressed. I basically want to make the actual program buttons static and make the skin buttons do what the program buttons would do (cycle through menus etc). I just want to make the skin buttons act accordingly. Sorry this is really vague, I will be grateful for any help thank you.

You basically need your application to handle the keystrokes generated by the skin's buttons. In your skin.xml all the buttons generate the same keystroke, so you'll want to change that so they are unique. I'd first hook up the key handling and test using the regular keyboard, then fiddle with the skin buttons to match.
