Yes.  Watcom can be hosted on several different platforms, including
Windows and OS/2, and can make any supported target from any supported
platform.  The list of available targets includes DOS real-mode, DOS
extended-mode (using the included and royalty-free DOS4/GW extender),
Windows 16-bit, Windows 32-bit (including Win32s), OS/2 16-bit, OS/2
32-bit, NetWare NLM, and Autocad ADS.

Watcom does include some tools that will limit you by platform.  For
example, if you write to Microsoft Foundation Classes (included with the
compiler), you can only compile targets for Windows.  Obviously, if you
write to the Windows API, the program will only work on Windows.  The
compiler itself, however, is platform independent.
