Ssh is able to tunnel and forward the X-windows protocol. Configured properly, you can call GUI-programs inside a ssh terminal session and get them started in a window of you local window manager while the program is executed on the machine, where you're logged in with ssh.
Or do you need a whole X-session executed remotely? All X-session managers, namely Xdm, gdm and kdm can do that. FreeNX is a server and client suite, that may do it as well, but is said to use far less network bandwidth per session than VNC.
