If you have trouble producing a whistle, look in the mirror as you try. Open and close the small hole between your lips ever so slightly, make it as round as possible. (Be sure your tongue is out of the way of the center hole.) Try tensing your lips into a more "pointed" pucker and vary your lip tension.
