[FEN "6k1/8/4qp1p/7P/6P1/5P2/6K1/Q7 w - - 0 1"]
I am unable to analyze this queen endgame in which it is White's turn. Is it a win or a draw for White?

I analyzed your position with Stockfish 11 ("Stockfish_20011801_x64_modern" to be exact) to a depth of 78 and it returned the following line as the best continuation.

As you can see by playing through the variation, no progress ends up being made and the game one way or another ends up drawn through the 50-move rule (I say one way or another because white theoretically could push say the f pawn at the end of the variation showed and restart the 50-move rule).
