If you draw your own control, it might help you to get started to make a very rough drawing of the control, one with no moving parts but with the areas of the control clearly delineated so you know where to do your hit-testing. Then draw your indicator with a black circle or square. Then draw the indicator with an image from a PNG. At the very end have a designer do nice graphics.
