Hi,

It seems the MVC & Morphic situatation will last for a while.

I propose an Abstract Factory one of the gof Design Patterns, for this.
It will become a list of standard widgets that are needed for basic operation 
of the system.
So Browser for example will build its GUI via an Abstract Factory, which
one will be decided by the project of course.

This provides to some extent an infrastructure for modularizing that
part of the system.

It can also help to build other gui's for example html-forms, and remote
images.
