You can see that there will be PC version, after v1.0. This is one of the goals that David set and it will be achieved. When, it is hard to tell.
In second thread I linked, there's description how to achieve working keyboard (I didn't checked that way, so I can't tell you more about it). And if you have working keyboard, you can program your gamepad to use these keys.
This all is hard, but it can be achieved. At least till there's official windows support that most probably would have "complete" windows support, which includes UI.
