Library Selection for OpenGL, CUDA, with UI

I’m trying to make a pretty simple application either in Linux or Windows. I’ve already written a fair amount of prototype code. Most of the program does calculations (currently not in CUDA, but will rewrite soon). The results are displayed using OpenGL (I used glut in my windows prototype). I’d like to make a user interface with a few simple buttons and an OpenGL window. I’d also like to use CUDA in the program. I’ve never made a UI before, but I’ve heard good things about QT. Guidance? Where to start? Templates?
