In this case you /almost/ don't need to know HTML, CSS, DOM, Ajax, etc.

develop WebUI and good PL lets you concentrate on problem domain instead
of
bothering about browser support.
It is a real pity that Haskell still has no such tools to generate Web
GUI
in Javascript. (((
Have you seen Chris Done's posts on the subject?

Thanks for the link! (Never seen this before)
Ideally, I would be happy to be able to write in Haskell a complete
front-end / GUI, so it could be compiled to different back-ends: Javascript
to run in the Browser and also a standalone app.
In Python world this is already done with Pyjamas (http://pyjs.org/) - "a
Rich Internet Application (RIA) Development Platform for both Web and
Desktop."
Also from Pyjamas site:
Pyjamas "... contains a Python-to-Javascript compiler, an AJAX framework
and a Widget Set API.
Pyjamas Desktop is the Desktop version of Pyjamas
Pyjamas Desktop allows the exact same python web application source code to
be executed as a standalone desktop application (running under Python)
instead of being stuck in a Web browser."

I wonder if somebody works on similar Haskell "Rich Internet Application
(RIA) Development Platform" ?
Any ideas, comments on implementation of such system in Haskell? What
existing Haskell GUI libraries can be used for a desktop GUI, etc.?
Well, it's basically just proof-of-concept at the moment, and it's not
really usable for real applications at the moment, but there is
http://hackage.haskell.org/package/dingo-core-0.1.0
http://hackage.haskell.org/package/dingo-widgets-0.1.0
http://hackage.haskell.org/package/dingo-example-0.1.0
The basic client<->server communication, server-side state handling,
etc. is there, but it's missing a couple of things before it could be
used for real apps: There's no real security, and there are *very* few
widgets. The few widgets that exist at the moment are also probably
lacking a few operations. On the plus side, it's should be pretty easy
to create new widgets.
You can get a feel for how the thing looks from an application
programmer's perspective by looking at the source for the example.
