Well, indeed there is quite good thing at www.amzi.com - Amzi Logic Server -
a Prolog compiler with more or less comprehensive API.

And Delphi. Although those provided there "language binding" are too straightforward
(in my opinion).

Yes, it is definitely possible, I have done that already.

I was planning to create Ada bindings for that Amzi Logic Server (and make
them publicly available) for about 2 years, and I'm still planning to do so.
But for the same reason (deficit of free time), I still didn't complete that
work. At this moment I think I have that bindings in a working state, but
they weren't tested enough, and the docs are slightly incomplete. I think that
the job may be completed in 2 or 3 weeks, but I'm not sure when I can afford
such a time for it. Perhaps, in coming May or summer.
  And I'd like to note here, that in the process of creating those bindings,
I became very dissatisfied with the Ada support for the character strings.
That poor support appeared to be a major obstacle for the design of the convenient
bindings.
