Good work on the tutorial prankster There are a few beginners tutorials on the Development section, but it's always good to have more

To anyone starting out with development, I'd also recommend checking out the gret newbie sticky tutorial on the development forum - http://talk.maemo.org/showthread.php?t=43663. It also walks through creating your first Qt Studio project and uploading to the N900. You might also want to check out the tutorials in my signature, they focus more specifically on playing sounds and using the accelerometer (for example). And there are lots of hints and tips everywhere on the maemo.org Development forum.. it's good to get ideas from everywhere

I think what mikecomputing is getting at is that QML is the bright shiny future and QWidget is on the way out the door as far as the Qt project goes. But there's nothing stopping use of QWidget on the N900, as you say it's still available and certainly not deprecated at this time.
