Hi Bob

I can't answer all your questions. Let me see what I can answer:

They're all implemented in C++. Depending on the control, much of it is 
implemented actually in the style, which is a C++ class deriving from QStyle 
and implementing the look-and-feel. On Windows, Mac and Symbian, it tries to 
use the platform functions to obtain the look of the platform.

Yes, they can. You can also download any updates from the network.
