It really has to be an OS X program. Think of it as something written
99% for the Mac, using pure Mac system calls etc, but one tiny corner
of the program actually calls into a Windows DLL to gain some
functionality, and tries to use winelib to get that access.
As an analogy, its a bit like fitting a Sony CD player into a Ford car
to replace the old cassette radio in the Ford, the Sony gives you a
better sound than the old Ford one would have done, but you don't have
to buy an entire Sony car to fit a Sony stereo...
I hope that makes things clearer...

I hadn't got that far, that seemed more complex than trying it as a
single Mac-built exe and a single Windows-built DLL. Yes you're right
that is what I ultimately want, but I was trying to start simple :-). I
have actually written a further application ready to call
simmpleapp.exe.so as a plugin, but haven't succeeded in building it
yet, I get some unresolved library calls.
