In a number of programs I've seen slider gadgets with knobs that
display the numeric value of the slider.  As you drag it around, the
number changes.

What is the right way to construct something like this?

I suppose that the number display isn't really part of the knob, but
is probably just some text displayed over an invisible knob and is
repeatedly moved around and updated.  I'd appreciate any suggestions.

BTW - are there any good tools out there for constructing fancy
composite gadgets like this?
