Ok so i didn't know where to make this thread, and this looked like an ok place for it.

so lets say that i have a bunch of C++ code, but i'm sick and tired of command promt, and want some graphics. now i don't want a windows window like you can get with a template in sudio.net, but like a full screen app. i don't want it to be platform specific repsonce, or a responce for linux and windows would be nice.

i know that to a certain extent i can do most things in C++, but what should i use to make menues and the such? should i pick up a basic or visual basic book or something?
