I am fairly new to programming for N900, but perhaps using the Nokia Qt SDK will work? It builds packages from QtCreator. It is also recommended to use if targeting the Ovi store.

From what I've read (and I may be misunderstood here), Madde is no longer needed. The Nokia Qt SDK 1.0 comes with QtCreator and everything else needed to target N900. There is also a preview version that has more features, Nokia Qt SDK 1.1

Good luck.
