What you are doing should work if putty is really forwarding, but if you 
intend to do much remote X work, I'd recommend installing the freenx 
package on the CentOS side and running the windows NX client that you 
can download from http://www.nomachine.com.  The only quirk I've found 
is that it generates a unique keypair during the install so you need to 
cat /etc/nxserver/client.id in a putty session, and cut/paste it into 
the nx client config (click configure, then the 'key' button).  It takes 
care of running over the ssh port for you and gives much better 
performance than normal remote X access.
