You can grab something like IDA or IDA Pro and decompile anything. Of course, your just going to get assembly language back (not the original C or C++ code). Their is another product from the IDA Pro people, Hex Rays, which applies some heuristics to create C code, but it's not going to be perfect.

Beyond that, I have no idea what the VFP++ compiler does. He may just be turning the P-Code into commands that make direct calls to the VFP runtime. Or something else. Craig likes to play lawyer, but without knowing the specifics it's impossible judge its legality or whether it violates some licensing agreement. As much as they'd like to make it illegal, reverse engineering is still legal.
