I'd like to write a small widget for my n900, it will query something every 5 seconds, and display the information in the widget on the n900 home desktop, it does not require performance or fast loading etc etc. I am sure Python is the way to go - But I have no idea how to start. What do I need to install? How do I make a PyQt APP to run? How do I port it to the N900, and how do I access on N900 API to get the information I want.
