From a first entry call your Build-function.
When created, pass it to the mode-map, i.e. redefine mode-map. Reload mode. Extended menu should appear.
And so on.
Below an example how to create a menu entry from a single known command in python-mode.el.
(defun emen (&optional symbol)
"Provide menu draft. "
(interactive "*")
(let* ((erg (or symbol (car kill-ring)))
(name (intern-soft erg))
(doku (if (functionp name)
(documentation name)
(documentation-property name 'variable-documentation))))
(switch-to-buffer (current-buffer))
(save-excursion
(insert (concat "\n\[\"" (replace-regexp-in-string "-" " " (replace-regexp-in-string "py-" "" erg)) "\" " erg "
:help \" `" erg "'
\n"))
(when doku (insert (regexp-quote doku)))
(insert (concat
". \"]\n")))
(skip-chars-forward "[[:punct:]]")
(capitalize-word 1)))
HTH,
Andreas
