See libavcodec/nellymoserdec.c theres a imdct some reordering, windowing
and stuff :)
Goal is a clean inverse transform of this transform. It has to be fast (no
O(n^3) matrix multiply!) good news is, all building blocks should be already
written (we have mdct, fft, ... code)
I also think you should write some selftest code to ensure that your transform
works correctly that is your transform -> existing transform is (nearly) the
same as what was input at the start.
And i think benjamin will want to comment on this / correct me ...

No, as long as you submit some application to google within time and finish a
qualification task within time (and you, like everyone will need several
patch submission review resubmission cycles so submit the qualification 
attempt early!)
