I would suggest you look into the MicroSoft "SDK" (Software Development Kit)
for Windows 3.0.  It runs with MSC 5.1 or 6.0.  Windows is about the only
graphics environment I know of which is similar to the Mac OS and QuickDraw. 
Even these will require some effort to port, however, due to many different
factors, CPU, compiler, etc.

Another approach might be to put AUX (Mac's System V Unix) on the Mac, and
AIX (IBM's System V Unix) or Xenix on the PC, if it is big enough (e.g,
386/486).

Lastly, you could work from the Macintosh MPW shell using ANSI standard
library functions, which behave pretty much alike in MSC 5/6, MPW 3.0, and
Unix.  This would not be a true Mac application, however.  It is a "shell
tool", sort of a vampire application which runs from the MPW shell, which is
the "real" application here.
