This little game doesn't look much like a modern GUI application. It uses some GUI techniques, but after you've worked through it, I recommend checking out the Application example, which presents a small GUI application with menus, tool bars, a status bar, and so on. There are quite a few very educational Examples. They are all written in C++, but are easy enough to follow since the point of them is to demonstrate usage of the Qt library, not C++ features.
