It sounds like you have very specific requirements, so you will
probably have to write the widget yourself.  However, I was really
impressed with Aaron Barth's ATV.PRO, which has a lot of the things
you want, primarily in the astronomy context.  Perhaps you could draw
inspiration -- or even code -- from ATV.
