title: Change words on tkinter Messagebox buttons
body: <p>I'm using tkinter's "askokcancel" message box to warn the user, with a pop-up, of an irreversible action.</p>
  
  <pre><code>from tkinter import Tk
  Tk().withdraw()
  from tkinter.messagebox import askokcancel
  askokcancel("Warning", "This will delete stuff")
  </code></pre>
  
  <p>I'd like to change the text of the 'OK' button (from 'OK') to something like 'Delete', to make it less benign-looking.</p>
  
  <p>Is this possible?</p>
  
  <p>If not, what is another way to achieve it? Preferably without introducing any dependancies...</p>
