Regular expression replacing in GNU emacs will handle this.  Here's a
sample function:

(defun prefix-region ()
  (save-excursion
    (save-restriction
      (narrow-to-region (point) (mark))
      (goto-char (point-min))
      (replace-regexp "^.*$" ">\\&"))))

The doubled backslash becomes one in the stored string; the & has to
be escaped.  Look at the dociumentation for replace-regexp, and in
Info under regular expressions.
