gtk-dialog-add-buttons (dialog &rest buttons)

dialog -- a gtk-dialog widget
buttons -- pairs with a button text and the response ID, which is a positive integer or a value of the gtk-response-type enumeration

Adds more buttons, same as calling the gtk-dialog-add-button function repeatedly. Each button must have both text and response ID. The Lisp implementation does not call the C function, but the gtk-dialog-add-button function is called in a loop to add the buttons.
