I posted a similar question for Carrara:
Is there an SDK out for Bryce, and on a related question, has Bryce been ported to Qt?
No SDK for Bryce.
Not sure what you mean by porting to QT. Bryce does make use of Quicktime though.
I think they mean Nokia's UI framework called QT. I have seen other vendors try it but not sure if any went RC (release candidate) yet.
