Is it possible to show the user a window just like the addon's setting window (aka settings.xml), only with custom fields and values that are generated at runtime?

xbmcgui.WindowDialog and xbmcgui.WindowXMLDialog classes allow you to create an arbitrary UI for your addon. First is pure Python but with somewhat limited capabilities, the second uses its own XML-based skin but provides more capabilities.
There is also PyXBMCt micro-framework that provides a convenient API for xbmcgui Python classes.

Thank you for the quick answer.
Your framework looks very nice and easy to use, I'll give it a try and play around with it.
