First off, I think fine is both the adverbial form and adjectival form of the word "fine" (wow, that did not make sense).
I am doing fine.
I am fine.
Well is an odd case. In Spanish, for example, you say "Estoy bien" (bien being the adverb, bueno being the adjective).
The real reason, I believe, is that you are asking "how?" How as a question implies the use of an adverb. "How are you going?" "I am going quickly"...or something to that effect.
Anyway, I like to simplify it to --> Well is the adverbial form of good. HOWEVER - well is also an adjective meaning "not ill."
"He has a fever; he is not well"
