Yes. if you wish to build a plain vanilla Unix app, that app
will build and run on both the Unix and the Win32 platform for
as long as you restrict your calls to the standard C/C++ runtime
calls and/or your own systems interface.

What kind of interface are you needing? The graphics interface
and the multimedia interface are different and therefore require
different calls. The system architectures are also different
between Unix and the Win32 API.
Are you really wanting to call Unix (Again, graphics or other)?
If so, then you will need to have at least OpenGL for Unix (for
graphics) as OpenGL is the only API that can run, with little or
no changes, on both the Unix and the Win32 based systems
If the former case (win32 based system platform), you will need
to write the necessary drivers, if they don't already exist.
ie. You will need to put together a gxx based application that
uses the appropriate drivers, etc.
Continuing in this vein, depending on the Win32 platform you
are targetting, there are different requirements in terms of
Recommendations at this time are to target either the win2k
platform or for a Win9x platform as these are the only two that
can handle the latest versions of DirectX (NT4 is no longer
being supported in terms of MS system certifications by MS.)
If, in fact, you would like to (or need to) build for NT4, you
will need to find a set of certain headers in order to support
the bastardized version of multimedia/graphics that currently
exists under NT4. There will be no more updates to the NT4
(system) multimedia/graphics levels past Service Pack-6 or -6a
(SP6-6a) with very few exceptions (most exceptions have to do
with lax internet security for Win32 API and involve the
installation of the weekly security patch releases from MS for
their internet based apps, both client and server).
There is no need to call Unix if you are building a pure Win32
interface and the -mno-cygwin switch is set.
Under the current version of Cygwin, (the -mno-cygwin portion
is currently being updated) you can use the -mno-cygwin switch
(gcc/g++) to invoke the mingw headers within the Cygwin
You can build a Unix console app (sans special Unix drivers)
that will run on a Win32 platform within the Cygwin API.
The Cygwin API was designed to function as an app which allows
the use of a Unix-like interface within a Win32 based system
