Perhaps this (based on the first version):

(defun mondu ()
  (interactive)
  (with-current-buffer (get-buffer-create "Mondu")
    (let ((make-desc (lambda (&optional description)
		      (insert (propertize (or description " NORM   ")
					  'face '( :weight bold
						   :slant italic
						   :background "lightgray"))))))
      (insert " MAIN PANEL DU \n\n")
      (insert " ")
      (insert-button "[-]" 'action 'mondu-outbd)
      (funcall make-desc " OUTBD   ")
      (insert-button "[-]" 'action 'mondu-norm)
      (funcall make-desc)
      ;;------------------------------------------------------------
      (insert-button "[-]" 'action 'mondu-inbd-eng-pri)
      (funcall make-desc " INBD ENG PRI  \n")
      (insert (spaz 24))
      (insert-button "[-]" 'action 'mondu-inbd-pfd)
      (funcall make-desc " INBD PFD  \n")
      (insert (spaz 24))
      (insert-button "[-]" 'action 'mondu-inbd-hfd)
      (funcall make-desc" INBD HFD  \n")))
  (pop-to-buffer "Mondu"))
