I should have mentioned two more things:

1. Once you're connected to the remote host any programs you start with 
X will be sent through SSH (obvious, I guess).

2. Your remote host has to enable X11 forwarding through SSH. Make sure 
its /etc/ssh/sshd_config has:
    X11Forwarding yes
if not, enable it, and restart ssh:
    /etc/init.d/ssh restart
