Watcom will give you single-source compatibility for any ANSI C program. 
It does not include cross-platform user interface tools, as you note.

However, it is compatible with nearly all such third-party user interface
tools on the market, including Zinc, zApp, Galaxy, and some others.  There
are also some freeware tools available for this, such as YACL.

Even with such third-party user interface tools, you still need a compiler.
