It should look more like this pseudo-code:

     already_have_a_letter_waiting = False
     for i in range(tbl_words.rows):
        for j in range(tbl_words.columns):
            if not already_have_a_letter_waiting:
	        letter = self.letters()
                button = Button(letter)
                button.border = BORDER_NONE
                button.padding = 0
                already_have_a_letter_waiting = True:
	    try:
		# here comes the stuff that causes the exception
                tbl_words.add_child(i, j, button)
                button.connect_signal(SIG_CLICKED, self.clicked, button, 
                                      i,j, letter)
                self.button_list(i, j, letter)
		already_have_a_letter_waiting = False
	   except PasteInWhateverExceptionYouGetFromYourTraceback:
		already_have_a_letter_waiting = True
