You have things in the exact reverse: an X client (application: e.g.
xterm), sends these requests to the X server (e.g. the XFree86 server,
Cygwin), which takes care of actually displaying stuff.

So, you can run X apps on almost any platform, as long as the server
they display to is on a supported platform; you can still run stuff like
Evolution on an S/390, provided it displays to a PC or something.
