Is it possible that you're mixing up Server and Client regarding X11?
The Server is the 'thing' (usually Keyboard, Mouse, Display) that
displays 'stuff' the Clients (programs that want output/input to/from
the Server) request.
So your GUI to the app would be the Client. Just give it something like
Xvfb as Server (maybe via the DISPLAY environment Variable) and it will
draw it's interface on the Xvfb Server (which is kind of a display in
RAM). Now, on the same Xvfb Server setup a vncserver to which your
client can connect to. No need to deal with the hosts hardware.

(of course, with a good connection, X11 Tunneling via ssh or remote just
simple X11 via the network might do the trick as well without the
Xvfb/vncserver setup)... Another option might be products like
nomachines nx or similar which i also got working within a vserver.
