Also, no, I don't believe GUIs are inherently difficult. I do think most GUI libraries are just terrible though, because they have bought into bad GUI paradigms. If a GUI is your example of something that is difficult, we are just living in different worlds and it's a challenge to have a productive conversation. I think a difficult task is something like "make this ambitious AAA game run on the PlayStation 3 performantly". That is pretty hard.
