**I'm not totally sure of this, but you might try adding another 
conditional to your while loop that can be toggled by a Scan and Stop 
button in your Tkinter app.

global ok_to_scan
ok_to_scan = 1 # or True
while (start_port <= end_port) and ok_to_scan:
    # ... do scan ...
    root.update()

then bind a function to a Stop button which toggles 'ok_to_scan' to 0 
(or False), also as previously suggested you should close the sockets 
that find an open port (sk.close()) inside your while loop.

HTH,
Marty
