All of this is possible.

dial_project_2 is just my GUI class. For example, the example that I 
give comes frome something like that
class dial_Projet2(QtGui.QDialog, Ui_dial_Projet2):
    ....

Ui_dial_Projet2 is a Python file created from a Dialog built with Qt 
Designer.

I hope that I'm clear.

PS : Maybe it is possible to subclass the metho tr(). I never try for 
the moment but it could be an easy way to implement unicode without 
doing boring changes.
