Try profiling it. I'm not an PyInstaller-user, but I could imagine that
loading Qt is pretty heavy. So you might try & import as few dependencies
as possible, as late as possible. That won't reduce the overall time
needed, but maybe get you going a bit faster so the user feedback is there.
In doubt - create a fancy splashscreen :P

There is no such thing I fear.
