The goal is to have an application that runs on top of all other applications and windows in the desktop, and display a clickable control (say, an image button) that moves around the screen.
The application must run as a service in the background and show thebutton (let's say) each hour, once clicked it disappears until the next hour.
This application has to be written in Python.
It looks like PyQt is one of the better options, but I'm not sure if it does support this sort of functionality and if it is a good alternative for modern Windows applications.
What packages or frameworks are appropriate for this scenario? I have seen Pygl and PyGame but they seem to be limited to a window, is this correct?
