No.  You're running a MS Windows program that knows nothing about X.
Cygwin's X server will not magically transform the output of Windows
programs into X windows locally or otherwise.

Don't do this.  It's not needed and it's not correct.

See above.

I think you're looking at the wrong software to solve your problem.  If you
just want to run Windows programs on other machines, you can always
try connecting to a shared drive on the server and running the installed
program from the client.  But you're not going to find Cygwin X helps you
do this.
