>In VFP, many of the tools and designers were written in VFP itself. I don't see why it would be different for Windows. Sure the core (kernel) needs to be written in C/C++/Assembly, but the user interface can be written in anything that runs on top of that.

Going way back, the early C compilers were written in C.
