If your dialogs reimplement QWidget::changeEvent() and handle QEvent::LanguageChange, that's already most of the work.
A call of QCoreApplication::installTranslator should then post that LanguageChange event, and your dialogs can handle that. You need to call installTranslator, yourself, e.g. if the user selects another language in a menu. Qt does not listen to OS language changes (yet), so if you were looking for that, you need to do that by hand.

Qt designer (4.6) lets you chose if a specific label text (or texts of other widgets) are translatable or not. Just uncheck the 'translatable' sub-property of the label text in the property editor.
