lets take a non be-verb:

lotlh = to rebel

lotlhwI' = the rebel

now, lets take a be-verb:

bel = be pleased

belwI' = someone who is pleased

Is my translation of the {belwI'} correct ? I am wondering whether the addition of the {-wI'} on be-verbs, functions differently from the way it does on non be-verbs.

Your translation is correct. -wI' turns a verb into a noun which is the subject of the verb. Exactly how that translates into English is irrelevant.
