Google "Simple Harmonic Motion" and see where that takes you. Just use the formulas (allow the user to input the individual values through textboxes or sliders) to calculate distance. You could try updating this once every few milliseconds/centiseconds.

You can use the Ball component, which needs to be placed on a Canvas.
