This is possible, yes.

Firstly, you should know that Nokia Qt SDK uses MADDE for Maemo development, so all the info about MADDE applies to it, too.

Basically, it would work with pkg_config somehow, but it is buggy in both Qt Creator and MADDE, so the workarund is to add the places of the libraries you need to the INCLUDEPATH in your project file, and adding the library names to the LIBS variable.

See this one for example.

BTW, you can join your fellow developers on IRC on freenode at #qt-maemo, they are very helpful.
