1. Download Xming
2. Download Xming-Fonts (this is not included in the straight Xming Download)
3. Download putty
4. Install above programs
5. Add "export LANG=en_US.iso88591" to you .bash_profile
6. Setup X11 forwarding in putty (Connection -> SSH -> X11) Click the Enable check box and add localhost:0 in to the X display location.
When I first set this up I missed the download of the fonts, once this was solved it all worked.
