Hi I am a Qt developer but never done any mobile device app.

I do the coding on windows xp, My question is

1. how do I make my qt app work in maemo?
2. i have n900 at my hand, i know the app manager in n900 will connect to repository somewhere in this website. if I have a app, how can i upload to the repository? any special requirment needed?

3. if i want to test the app on the device, how do i get the app onto device? through repository?

thanks very much. i would love to start to learn how to develop the apps for maeno, please show me some lights
