With a propeller engine, the "wind" is a side effect caused by to the primary effect of the props getting "lift" in the forward direction, similar to how the wings themselves work. The prop itself is a wing [1], which twists to create even thrust across the prop despite the speed differences between the root and tips.
Turbofans (and ducted fans) are different, as they really do produce thrust due to the particles they are throwing backwards (direct thrust).[2]
Turboprops can get reverse thrust by inverting the propellers, but adding a thrust reverser behind them would not be enough to negate the forward lift (though they could cause problems with the airflow over the props that would negate the forward lift - but it wouldn't be due to the redirected airflow).
