ANE with native C++, Qt

I am trying to write a simple ANE for BlackBerry that will read a phone number, and return that to the actionscript layer. To read the phone number natively, I need C++ and Qt.

I can't even figure out whether this is actually supported for an ANE. I cannot find any examples for BlackBerry that use C++ in the native portion of the ANE. I only find the suggestion that function name mangling in C++ may prevent an ANE from working and generate the error 3500 "The extension context does not have a method". I don't see why this should be an issue because we define a string -> function map.

Can anyone tell me whether it is currently possible to use C++ and Qt in an air native extension?
