[Discuss-gnuradio] Changing GUI structure on the fly

Hello 

I have a question: I have to program one application, that will switch between about 20 modulations.

With 20 modulations, program will have a lot of parameters to change, so GUI needs to change during runtime. 

Is it possible to do somethink like that ??

Are there any design patterns for problem like this ?

Many thanks
