I wrote a simple GUI using C++ a while ago, just for my map editor. It's primitive and only has the absolutely needed widgets (buttons, textbox, one-layer menu which is essentially a button and maybe a couple others). Then I realized how difficult it is to get one right. I think QT is easy to use and C# is another option on Windows.
