Hello Micheal, I have thought a bit about Genode chat clients, and I think the first concern is to seperate the crypto that protects a conversation from the GUI. If the critical code is isolated in a non-graphical component and a graphical frontend can interact with this core using something like a file system, then isolation of conversation GUIs should not be much of a concern.
Running Nitpicker recursively is possible and practical in some cases, but it may actually weaken isolation as in the recursive case you would have multiple clients drawing to a common session, whereas in flat Nitpicker each client enjoys equal privacy. I don't want to discourage you though, a Qt chat client would be great. I got as far as porting the Tox library and implementing a very simple terminal interface, but I don't think I will have the chance to work on a Qt frontend in the near future.
