Yeah there's a bit of a learning curve because it's trying to put full DAW capability into a tracker. I don't use Windows so I've never tried OpenMPT but I started out using ScreamTracker and ImpulseTracker, used Jeskola Buzz for a while.
I found this today, a tracker that runs in a web browser, looks like it can import/export files etc: http://www.stef.be/bassoontracker/
