Starting an Extension on Startup

What I'm hoping to achieve is that as soon as Thuban is opened a dialog
box will be raised by the extension prompting the user to "login". The
extension will then be used to do populate a database with information
about existing features and (probably) do some digitisation.

I understand that extensions get executed when they're imported and that
I can initialise things in there however I'm not sure how I can start
displaying dialogs unless I know what the parent window is, which would
come from the context object which isn't present when the extension is
imported?
