I use it regulary in my plugin. For example, there's a very useful class:
QSqlQueryModel, you write a query and you can "push it" results in a
QTableView automatically (no need to define columns, iterate over records,
etc). See all QtSql classes here:

(it's QT 4.5, the same version of the windows QGIS 1.5 distribution).

Yes, but if you want to distribute that plugin "worldwide", using the QT
library is a better option.
