Most of the code there should no longer be necessary -- you don't need
to fetch the labels separately if X-GMAIL-LABELS is already in
`(gnus|nnmail)-extra-headers'. It might be enough to do:

(defun gnus-user-format-function-g (header)
  (let ((g-labels (cdr-safe
                   (assoc 'X-GM-LABELS
                          (mail-header-extra header)))))
    (when g-labels
      ...do something with labels)))

Then use the "%ug" format code in your summary line format. I have no
idea what the Gmail labels actually look like, so I can't help you with
how to output them, but that should be the easy part.

I don't believe there's any way to actually manipulate the labels from
within Gnus, though -- I suppose they're different from regular IMAP
flags/keywords?
