You can run vnc-server on your Centos Machine. A very good document can be found on the CentOS wiki http://wiki.centos.org/HowTos/VNC-Server
Also, you can get an Xserver like http://sourceforge.net/projects/xming/
This would allow you to connect to your CentOS machine's X server and display a window (or smaller windows) on your Windows host.
