PyQt and MVC-pattern

I am trying to design an MVC-pattern with PyQt. I want to split all programs into 3 parts:

1. classes abstracted from all Qt classes (model)
2. classes providing data from the model to a Qt app (controller)
3. the Qt app itself with defined method SignalsToSlots that connects signals with controller.

Is this optimally? What scheme is recommended for use in PyQt development?
