There are some ethical implications involved with using an IFrame to import someone else's content and treat it like it's your own. I'm willing to bet a) this goes against Wikipedia proper/intended use policies, and b) they probably have this blocked or will block it quickly as soon as they find out it's happening (it's all tracked in logs).
But I get the impression OP is looking for the raw application itself to populate with his own content, not for the inclusion of the current Wikipedia itself. Is that correct?
I'm sure you could open the tarball on your server, and you can do it in Windows as well. Just do a search for a compression program that handles this format. Recently, I've been using FilZip, a nice little program, IMHO. From there, you should find installation instructions to guide you the rest of the way.
