Does the following function do what you want?

(lambda (env &rest ignore)
  (LaTeX-insert-environment
   env
   (let ((lower-left (read-input "(Optional) Lower left corner (x0,y0): "))
	 (upper-right (read-input "Upper right corner (x1,y1): ")))
     (concat (unless (zerop (length lower-left)) (format "(%s)" lower-left))
	     (format "(%s)" upper-right)))))
