I presume you've already got hold of Erik Meijer's cgi script stuff.
(If not, there's a copy in the current Hugs distribution at
http://haskell.org/hugs.)
I'm afraid I'm not familiar with most of the other things you want.
I know GHC (another Haskell compiler) provides an ndbm interface
but AFAIK it's not (currently) portable to other compilers.

Nothing wrong with reusing existing code. Here at Yale we're very
interested in interoperability with C, C++, etc. because it's
unrealistic to expect every library to be (re)implemented in Haskell.
One approach to interoperability is GreenCard
(http://www.dcs.gla.ac.uk/fp/software/green-card/)
- a tool/language for describing C functions in the way Haskell
programmers want to see them.
Another approach is to use IDL (cf COM, CORBA, etc) - which lets you
describe functions (in any language) in a way that programmers (of
any language) want to see them. SimonPJ's
paper about COM (see http://www.dcs.gla.ac.uk/~simonpj/) is a good
place to look - but note that they're not distributing an
implementation (yet!)
Of course, it might be that the Java libraries aren't powerful enough
to do the job or force an unnatural programming style on Haskell
programmers. In that case, we should think about implementing them
ourselves.
