No, it would not. Air flowing over the wing creates lift. However, if you ever played with a rubber band aircraft, you'll remember that if you really cranked the rubber band up, you could hold the plane with the propeller facing the sky and the propeller would create enough lift (briefly) for the plane to increase altitude. Not unlike a helicopter's rotor.
