Unfortunately, you can't. Not that way. Eventually the Nokia Qt SDK may support Symbian code but not at present.
Follow this roadmap to install the Carbide kit: http://developer.symbian.org/wiki/in...tandalone_SDKs
Carbide can also do Qt, and IMHO is the superior environment (multithreaded build, etc).
So why not give it a stab?

You can make a Qt application that runs on a Symbian device with the "Qt SDK for Symbian" or whatever it's called. What you can't do is mix Qt and Symbian C++ using that kit. To mix the two you need to use the Carbide lashup I pointed at.
