The following code should handle both words at point and region. Just do
"M-x google" or "C-c g" + ENTER.

(defun tma-word-or-region-at-point ()
  "Return the word or region at point."
  (if mark-active
      (buffer-substring (region-beginning) (region-end))
    (word-at-point)))

(defun tma-interactive-with-default ()
  "Allow a user to enter a search word or phrase, but give a sane default."
   (list (let* ((default-entry (tma-word-or-region-at-point))
                (input (read-string
                        (format "Search%s: "
                                (if (string= default-entry "")
                                    ""
                                  (format " (default %s)" default-entry))))))
           (if (string= input "")
               (if (string= default-entry "")
                   (error "User must provide word or region.") 
                 default-entry) 
             input))))

(defun google (word)
  "Use google to search for word or region."
  (interactive 
   (tma-interactive-with-default))
  (browse-url (concat "http://www.google.com/search?q="; word)))

(global-set-key (kbd "C-c g") 'google)
