To make a "simple" window requires about 70-100 lines of code, so it's not a walk in the park to create a fully fledged program. Even creating a text editor (like notepad) takes a bit of effort. But it is heaps easier to understand Windows programming after doing some C/C++ programming for a while. You will eventually have to learn some C anyway, as both Win32 API programs and MFC are based on C.
