I would say the console has little role in this, apart introducing the Qt
dependency.
Since we have introduced win_... family, eventually I would prefer to
extend the family (something like win_web_console...)

Opening a WebKit browser it's matter of a couple of lines (we can start in
literally 10 lines :), but IMHO the interesting part would be about
seamless integration with current prolog stream IO.
In the past I ported (part of) an RDF/XPCE application to HTTP, and can't
say that programming a GUI it's really easy...
Maybe today things are better, thanks to Anne tutorial (sorry Annie, I
didn't tried it, because it come after I completed my task...).

Anyway, apart QtWebKit, also the current console has HTML capabilities.
Then exposing the DOM through reflection could be rewarding.
I've begun to follow this route for easy things like line wrapping, max
block count, fonts, colors....
