It may be the case that Red was created for the reason you state, but it simply doesn't appear to have the necessary momentum. And that's unfortunate, because REBOL does not have a lot of interesting and smart features, such as having mini-DSLs ("dialects") for things like GUIs.
To date, Red can't even run without already having REBOL installed on your system. The project has been around for almost two years now, and only a few days ago has it successfully been able to do the program "print 1".
Red was announced and started last year in March. It's basically 2 languages and until last month development was going towards compiled low-level dialect Red/System. I was actually impressed by speed of things moving in Red/System and many members of small REBOL community contributed to it. (It had GTK bindings, ZMQ, port to android, while it was still in development).
The announcement this week about "print 1" is about the fact that now the "Red" (higher, rebol-like level) language is also at the brink of working.
