Qt has a guide to internationalization, which includes the basic information: to wrap your string in a tr function call.

label->setText( tr( "Hello, World!" ) );

In addition to this, if you want the language to change on the fly, you'll need to identify when the context has changed, and update your labels appropriately. Unfortunately, I can't easily put my hands on the signal that indicates when to do so.
