Hey guys. I am wanting to make a little handheld, touch screen pong game, and possibly more in the future. So here are some questions I have.

Is there a way I can use a very very minimal install of windows, just enough to run a EXE file? If not what language would I have to program my game in?

Hardware, any online stores you guys know of I could get the hardware.. I don't want a pico-ITX board, I'm not trying to make a computer >:O

Just, any help would be nice.. I can do the soldering and etc, I'm a computer technician, but I am not familiar with making my own handheld!

Thanks for any help ^-^
