Hi -
It depends on what you mean by "view".
File sharing is incredibly easy. Just Google "samba howto ubuntu":
EXAMPLE:
https://help.ubuntu.com/community/SettingUpSamba
Actually displaying your *nix GUI directly on Windows is also do-able (but, IMHO, a bit more complicated than it really needs to be). Google for "xvncserver howto ubuntu". For example:
EXAMPLE:
https://help.ubuntu.com/community/VNC
<= Since you mentioned VNC, this is probably the option you want
And you can also install X Windows directly on your PC. Google "CygWinX howto":
EXAMPLE:

'Hope that helps .. PSM
