recommendation for UI-driven web-framework (php/jQuery)

i've read some threads on stackoverflow but couldn't find a solution. we're looking for an opensource (preferred) framework which is well supported (plugins, addons) and has widgets (ui components) for building full-fledged, complex web-apps. it's required for building complex web-applications / cms-systems.

it should be php + jQuery based and most of all - light weight (+ easy to install on webs开发者_C百科erver).

we are requiring the following ui widgets: - standards (textbox, select ..) - datagrid (should be bindable to a database) - image- and fileuploader - several gui containers on one page

i'm thinking about something which has gui and code separated (like asp.net - just for php)

thanks in advance
