XQuartz might be of interest to you. It used to be included with OS X in older releases but is an external download now. http://xquartz.macosforge.org/
After you've installed it, you can test that it works by typing
xeyes
in your terminal. That should show two googly eyes.
Then ssh to some other machine with X forwarding enabled. To do that, ensure the remote host has
X11Forwarding yes
in
/etc/ssh/sshd_config
then
ssh -X example.com
Assuming the server has the necessary X11 libraries and xeyes is installed on the server, you can once again type
xeyes
and you'll see the googly eyes again but what you are actually seeing is them running from the remote machine.
Hope this helps though I'm not sure it is quite what you're looking for.
(Personally, I use X forwarding very rarely, prefering the terminal for almost everything but browsing the web.)
