This works for me:

 (local-set-key [escape] (lambda ()
                           (interactive)
                           (message "Escape test")))

Of course you want to do something else then sending a message, maybe
something like (delete-frame) or (bury-buffer).

Also, you probably want to add the key to a certain key map. This is
what I do for my jabber client:

 (define-key jabber-chat-mode-map [escape] 
   'my-jabber-chat-delete-or-bury)
