You can bind <Destroy> and act accordimngly, or intercept the action
altogether.

Example:
-----------------------------
from Tkinter import *

def killingAction(ev):
    print "Destroyed"

def kidding():
        print "not killing"
        l.config(text="just kidding")
        l.master.protocol("WM_DELETE_WINDOW",original)

l=Label(text="Kill me!")
l.pack()
l.bind("<Destroy>",killingAction)

original= l.master.protocol("WM_DELETE_WINDOW",None)
l.master.protocol("WM_DELETE_WINDOW",kidding)
l.master.destroy=lambda: 0

mainloop()
--------------------------------------------
