I'm primarily a server-side developer - not even web server stuff. But I'm finding more and more that I need to mockup user interfaces. This is in part to more senior roles doing overall product design, but there is some personal interest as well.
I'm wondering what would be a good UI toolkit to learn. I won't be making production user interfaces, and doing them as web apps would just be fine. I've been leaning towards learning jQuery as it has a graphing library I like to use (flot). Someone else at work is suggesting EXT-GWT.
Is there anything else out there? For straight up mockups I use Balsamiq, but sometimes I want to go a little past plain mockups and add some functionality.
Thanks.
I haven't used anything a lot except jQuery.
It has been great especially when you start using the UI and theming which makes quick work of standard things. It'd be a problem if you wanted anything outside the box because then you'd have to find a plugin or write your own. (both of which are fairly easy IMHO.)
