I was looking at Qt. The developer license is pricey but probably doable. 
What does it provide for the kinds of controls I mentioned? Do you know of 
any demo apps I can look at that illustrate how well they function?

As an example of the kind of app I'm thinking of, consider a model train 
control panel which can control the speeds of various locomotives and 
report track conditions in real time (eg. graphing the impedance of the 
tracks).

For an example of the kinds of controls I'm looking for, National 
Instruments' Measurement Studio is an instrumentation GUI control library:

And as you can see, there's no Linux port.
