Making a desktop app using the ParaView framework


I want to make a desktop app using the ParaView framework. I basically want to make a simpler ParaView GUI.

I want to know if this gui has to be Qt-based or I can use any kind of technology.


Yes. See Examples/CustomApplications in the source repository.

Adding to what @mwesphal said, if you want to just simplify the existing interface, then probably the least development work involves using Qt in your application and referring to those examples. But it is possible to use other GUI frameworks that do not depend on Qt (see ParaViewWeb, for example).
