I have experience from writing code with a graphical user interface
that runs on either UNIX/Xwindows/gnu-C++ or stand-alone DOS/Windows/MVC++.
This is possible due to the fact that X-windows is designed to run
on any environment, including Microsoft Windows, and that the
MVC++ compiler supports most of the UNIX system calls.
All you need is some X-Windows server on each environment, the
knowledge and skill to program for X-windows, and users that accept X-windows 
behaviour inside your application. Otherwise the application behaves and
looks just as any other MS-windows application.

The X-windows product I used was eXceed4 from Hummingbird. It is now named
eXceed5. There are probably eXceed5 for OS2 and Mac as well, or any other
X-window server for those environments that will server the purpose.

The porting of the actual C++ source code was very simple in my case.
A few changes to support DOS filesystem, and such things.
Only the existing C preprocessor is needed, and a few ifdefs.
