You would have to dual license your .ui file so that you could use it in 
your script without the GPL infecting it. Other users of the .ui file 
could then only use it in GPL-compatible code (I assume that is your 
intent). As your own script would not have a GPL-compatible license 
(otherwise what's the point?) you would need a commercial PyQt license.
