Remote GUI help requested

I'm real close to a solution, but I could use one last bit of advice
WRT being able to get the default Fedora GUI "DESKTOP" popped back
to my home PC running Windoze.

I use Secure-CRT to SHH into the Fedora box with X11 forwarding enabled.
I am running Exceed on the PC.
I can successfully invoke xclock & similar utilities on the Linux box
and get the display on my home PC. YEA!

I could use a clue or two on exactly what I need to (setup?) and
invoke to get either GNOME or the KDE "desktop" to appear on my
home PC?
