And if not SQL, why not writing into the good old QFile with Qt serialisation (http://doc.trolltech.com/4.6/qdatastream.html) instead of mis-using QSettings (yes, *settings*, which are meant to store application *settings* instead of data ;)?

You can already write/read quite a lot of datatypes with a simple << (respective >>) "out of the box": http://doc.trolltech.com/4.6/datastreamformat.html - including a QMap where you could store all your Country/Capital values.
