This is a very pretty study. I didn't think the first move was all that hard to find- it was my first idea once I had absorbed the position, but it took me quite a while to prove it was the only win. How quickly can you do it?

For example

1.Qg8+ Ke7 2.Qc8 Qb1 3.Qd7+ Kf6 4.Qd8+ Ke6 It's a draw.

White can't make any progress.

1.Qg4 Qb1 2.Qd7+ Kf8 3.d4 Qg6+ 4.Kh4 Qh6+

White can repeat perpetual check, but white can't win.

And why do moves like 1.Qg4 or 1.Qg8+ not win?
