Hi,
for the first question, look at the following links:

For the second and third questions, I don't think it's possible to create new controls on run time, so you should use a trick for doing it. Maybe you could have the rings created previously but keep them invisible, and just show up when necessary. For accomplishing it, use property nodes of the ring controls such as visible and position properties.
