Piuh. That's quite difficult. The point is, that the Windows-Architecture is
32-Bit while the DOS-One is 16-Bit.
So writing this program (if it's quite trivial) is possible, BUT you have to
compile two versions (for DOS and for Windows by using variois ifdef
directives).
But I'd rather recommend writing to different ones with the same backend. If
you restrict the GUI to one file and use a nice makefile you can work with
the same sources)
After that, you can use a wrapper-batch to start the appropiate program.
