[erlang-questions] GUI development with Erlang

[Joe Armstrong]

If you want something that just works and is reasonably simple to implement
Browser based GUI's are pretty good.

The combination of web sockets + SVG/Canavas/DOM manipulation in JS
is pretty easy to setup and loads of people understand JS/Browser things.

Stand-alone outside the browser is tricky.

TCL/Tk is really easy to get going and interface (yes it's old but works
well)

Java Swing is what it is - and if you're good at Java might be an
alternative
but you'd have to interface it to Erlang.

QT is brilliant but you'd need to write the GUI in C++ and interface it to
Erlang

WxWidgets is actually pretty good but has a steep learning curve (a cliff) -
I did actually manage to build some interfaces with it and concluded that
it was pretty good but that it needed a *lot* of examples and getting
started
tutorials.

Cheers

/Joe
