Or, slightly more simply:

#+begin_src emacs-lisp
(with-current-buffer "my.org"
    (apply '+ (org-map-entries
                   (lambda () (if (eq (org-outline-level) 1) 1 0)))))
#+end_src

which you could wrap into a function like:

#+begin_src emacs-lisp
(defun count-toplevel-headlines ()
  "Count the top level headlines in the current buffer"
  (interactive)
  (message
    (format "Number of first level headlines: %s" 
      (save-excursion
        (apply '+ (org-map-entries
           (lambda () (if (eq (org-outline-level) 1) 1 0))))))))
#+end_src

Best,
Richard
