The WinAPI&#x27;s closest analog in Unix-land is POSIX, which is just as horrifying. Gtk+ vs. WinAPI is apples to oranges. IMO, even WinForms and Visual Studio&#x27;s form designer are infinitely better than the mess that is Gtk+ and Glade. I haven&#x27;t tried Qt too seriously, but my impression of it is that its object model combines the disadvantages of C# (less than adequate support for generic programming) with those of C++ (manual memory management, not even aided by smart pointers).
