What do you program GUIs in?

Everything seems to be in C++. Is that what /prog/ uses too?

The command line program "convert" allows you to crop, rotate, scale, transform(, etc etc) images.

I can splice, convert, combine, and modify video with "ffmpeg".

Anything beyond that I wouldn't know how to do anyway, so anything that I need to do I can do through the command line.
