Erlang and GUI

[Alex Peake]

Sorry to ask about this again.

I read in the PowerPoint presentation "Concurrent Functional Programming with Erlang and OTP" by
Bjarne Däcker that (in the section on Carrier Class apps) "Operator GUI applets" were written in
Java.

Is this the best way to develop apps that have a significant Graphical User Interface element to
them?

(I looked at "gs" and find that it is the (somewhat limited relative to the MS Windows world with
ActiveX grids, trees, etc. "widgets") tcl/tk).
