Add button to existing universal iOS app

I require a developer to add a button (PNG format) to my dialog boxes in an existing iOS universal app (iPhone, Retina and iPad). Also I need audio clip "your session will...." that plays before dialog appears to play when the button is touched. Lastly, once the button is touched it should close dialog and bring user back to main menu and continue playing audio session.
