iTunes OLE interface points to iTunes Scripting Interface which in turn points to the Apple iTunes COM SDK, which likely is what you want to use.

I don't know why there aren't many iTunes modules, but maybe most people automate iTunes through AppleScript and it's just so trivial there that nobody thought of encapsulating it in a module.

On second look, Plagger::Plugin::CustomFeed::iTunesRecentPlay looks promising and has Win32 support too.
