I did something similar for Muse recently.  I'm including the code
snippet in case it comes in handy.

;;;###autoload
(defun muse-publish-region (beg end &optional title style)
  "Apply the given STYLE's markup rules to the given region.
The result is placed in a new buffer that includes TITLE in its name."
  (interactive "r")
  (when (interactive-p)
    (unless title (setq title (read-string "Title: ")))
    (unless style (setq style (muse-publish-get-style))))
  (let ((muse-publishing-current-style style)
        (muse-publishing-p t)
        (text (buffer-substring beg end))
        (buf (generate-new-buffer (concat "*Muse: " title "*"))))
    (with-current-buffer buf
      (insert text)
      (muse-publish-markup-buffer title style)
      (goto-char (point-min))
      (let ((inhibit-read-only t))
        (remove-text-properties (point-min) (point-max)
                                '(rear-nonsticky nil read-only nil))))
    (pop-to-buffer buf)))
