well, good, wohl, & gut

Seems like a good intuition to start from, I have no objections.
A query in an online dictionary (LEO) brought about some interesting
results that inspire for a more thorough investigation of the semantic
fields of "well", "good", "gut" and "wohl": 

done good -- gutgetan
to do good -- wohltun
good deed -- die Wohltat / die gute Tat (which are two very different
concepts!)
to feel good -- sich wohlfühlen (I did not find "sich gut fühlen" -- but I
would certainly use it in certain contexts; however, it is certainly not
equivalent to "sich wohlfühlen")
to sell well -- sich gut verkaufen
to bear oneself well -- sich gut betragen
good -- das Wohl (e.g. common good - das gemeine Wohl/ Wohl der Gesellschaft)
good -- das Gut (e.g. fragile good - zerbrechliches Gut)

At first sight, and corresponding to intuitions, the semantic range of
"wohl" seems to be quite remote from that of (adverbial) "gut".
