Well here's GTK hello world in freaking C. One file that you can gcc and run "./a.out". Not 79 files with a build system that breaks every time you hit "upgrade", and which requires me to install gigabytes worth of SDK API bloat and agree to 10 different license agreements. Want a free build system that works for this for every version of Linux in the past decade and probably the coming decade? All you need is ONE "Makefile" and you're done.

Any higher level language and ecosystem than C should be less verbose and less involved than this. Otherwise, what's the point of being higher level?
