Lost in the VNC

This time I am a bit lost with VNC :(

The idea is that I need to make a kind of remote access to the workstations (Win XP) in the NAT from outside and one way to do it (as I thought) was to set up a VirtualHost on Apache (of course with SSL and Auth and all the rest) and then use mod_proxy and VNC web client to do the job.

Everything would be fine if VNC Java applet would give me to do this, but it doesn\’t work pretty good through proxy :( Anyway, after playing around a VNC Web client I realized that it is not too comfortable so I need to find some other (prettier) solution to this problem.
