Best webifier for green screen applications

We mainly use Infor LX, and quite a few custom green screen programs in a
manufacturing environment. There has been some interest in making
everything look GUI. What are some good solutions to get there? Ideally I
guess I'm looking for something that initially scrapes everything to web
without modification, but also allows some enhancements as time allows for
concentrating on groups of applications to make the GUI actually worth more
than the initial interface repaint.

Years ago, I think the thing that came closest to what I was looking for
was IBM's HATS product. I haven't heard much marketing around it lately,
so I fear that it may be supported, but not enhanced significantly anymore.
I could be wrong on that, but its difficult to sort through the marketing
speak to find out how usable it really is. That's why I'm here, asking for
some overview of what's available and what works with a production
environment.
