What's your exact problem with the MinGW build instructions in our wiki? I mean when you follow them step by step it will work (unless I'm leaving out important information that I assume to be well-known or something). The only thing you have to take care of yourself is setting up the environment (including environment variables).

Another option would be installing an OS that's better suited for development like some Linux distribution (everything you need can simply be installed through packages). Some of them already have ready-made build rules in QMC2 and tested instructions exist in the FAQ. Why don't you simply prepare a virtual machine for that (using VirtualBox or whatever)? Of course, you can also stay with Windows here, even though that wouldn't be my personal favorite wink... I keep a number of VMs myself to test/support the different OSs and distributions.
