The "Self Insert" command does something like (this is pseudocode and from
memory):

   (let* ((key-event (get-last-key-event))
          (char (get-character-from-key-event key-event))
          (point (current-point-for-insertion)))
     (insert-character point char))

e.g., the whole idea is to insert the character associated with the last key
event.  (The real command takes a parameter - an optional repeat count - and
may call INSERT-CHARACTER more than once if that parameter is a positive 
integer.)  That isn't what you want here, but it's similar.

(defcommand "Insert Left Double Quote" (p)
   "Insert a left double quote character at the current buffer's point,
    deleting any selected range before doint the insertion."
   "Secret doc string for developers"
   (setq p (or p 1))
   (let* ((point (current-point-for-insertion)))
     (dotimes (i p)
       (insert-character point #\u+201c))))

(defcommand "Insert Right Double Quote" (p)
   "Left As An Exercise"
   "Guess, but a right double quote is #\u+201d ."
)

(bind-key "Insert Left Double Quote" #k"meta-{")
