There is a MiniProlog that comes with the Haskell interpreter Hugs
<http://haskell.org/hugs/>, which is OO, and therefore easy
to translate into languages like C++ and Java. For the Prolog interactive
query style, it relies on laze evaluation, so that goes out of the window
when translated into a strict language. And I recall the cut was wrongly
implemented (but easily fixed).
But you might take a look at that one, to see how this stuff is implemented.
