Re: [Jython-users] Re: Browser UI Application

[Tom A. <tw...@po...>]

George,

I'm am Jython beginner but I can recommend Swing based GUI loaded via 
webstart.  Your target audience will have to have the java run time 
installed but after that things do 'just work' (well, most of the time 
anyway).  You get get a very painless install, a free update service 
(update the server and all your users get the new version the next time 
they start up) and your users have a rich client with all the benefits. 

Also Swing is a pleasure to code in Jython.

Cheers

Tom (a different one)
