Here's what I've figured out so far (it seems to work), is it
the recommended idiom?

class FooBar(GtkDialog):
    __super = GtkDialog
    def __init__(self,msg,buttonTextList):
        self.__super.__init__(self)
        self.__returnString = None
        self.set_modal(TRUE)
        [...]
        
    def clicked(self,buttonWidget,buttonText):
        self.__returnString = buttonText
        self.destroy()
    
    def wait(self):
        while self.__returnString is None:
            mainitereation()
        return self.__returnString

The important thing is that mainiteration blocks until it
receives an event -- this is the default behavior.
