To have your window display on one remote machine can be done as follows:

Set the environment variable DISPLAY on the machine on which the code runs as:

% setenv DISPLAY machineID:0.0

where machineID is the name of the remote machine.
On the remote machine whose name is machineID, do

% xhost +

which will allow access to all machines to open windows on it. You can also
give the above command followd by the accessing machine name to let only that
machine access it.

Now if you run your program on the first machine, all windows that it opens
will be directed to the second remote machine.

Hope this helps.
