For a project at work I need to write a screen saver that'll load a web page which logs the lab computers out of the network. (We run a very expensive propritary captive portal which luckily provides a static log-this-computer-off link) It'd also be nice to throw some photos up, but that's inconseqential.

I've written plenty of unix command line progs in C and Java, but have no windows programming experience. I can follow this tutorial easily enough, but is there any free way to compile the things?

Thanks,
Matthew
