QT: translation using button

Hello friends,
I am creating some labels and information box in qt designer. Also i have created a push button for translation purposes. QT has &tr for whichever text can be translated to other language. Is there any way to connect this to the push button, where a drop down menu will tell the language choices. Or is there a way to save the translations somewhere and then bring them at the click of the push button. Kindly let me know. Thank you for your time.
