I'm looking for free UI lib/sdk/framework to make openlayers app that I can have the map in one panel , the layer control in other panel and maybe hovering tool bar (instead of putting buttons on the map). Bottom line , I'm looking to easily and fast make good looking and practical UI wise app. Thx!
I would have guessed this has previously been asked, but there are a couple of these. GeoExt seems reasonably popular, and is probably a good choice if you have any ExtJS background.
In general, you are probably better off deciding which framework you want, and then typing that name plus "geo" in a search engine. So the top hit for me on "jquery geo" was http://jquerygeo.com/ (where do they get these names!) which I have not tried, but might suit you.
