Answer 1

Qt Quick is a declarative, smartphone-style user interface with support for a lot of the cool animation transitions that are common in smartphone apps. Qt Widget is the traditional desktop-oriented UI model. Right now (pre-Qt5), Qt Quick support for desktop system features is lacking (but improving).
