Many thanks for the pointer, I think it will solve my problem, so what I can do to
have two strings translated in different languages is:

locale = "it_IT"
italianTranslator = QtCore.QTranslator()
italianTranslator.load("myapp_" + locale, ":/translations/")

locale = "fr_FR"
franchTranslator = QtCore.QTranslator()
frenchTranslator.load("myapp_" + locale, ":/translations/") 

button1.setText(italianTranslator.translate("", "Label 1")
button2.setText(frenchTranslator.translate("", "Label 2")
