Yup. Mutiple ways actually. 

The first method you can use is to set the DISPLAY enviorment variable on
the computer you are running applications from. export
DISPLAY=address:display (export DISPLAY=192.168.1.10:0) then when you run
the program it will display on display 0 of 192.168.1.10, provided xhosts
allows access. (man xhosts)

You can avoid xhosts and setting DISPLAY enviorment variables all together
by using ssh. Simply ssh -CX user at host. This should enable automatic
Xforwarding over an encrypted ssh tunnel. Secure and easy. The -C adds
compression, also useful.

Lastly you could enable XDMCP. XDMCP allows you to query the display
manager and get a gui logon, just like you were sitting at the server.
Start your Xserver with the -query host option to get the logon screen.

If you're allready logged in, you could use Xnest to get a desktop in your
desktop, just Xnest -query host. (Good for testing too.)

Overall, the ssh method is easiest. I belive adding X11Forwarding yes in
/etc/ssh/sshd_config will automatically turn on the redirection when an
ssh client connects, so you don't have to give your ssh client the -X
paramater.

Hope that is somewhat helpful..
