[jQuery] Re-implementing Ext-js webapp using jQuery

I want to use jQuery to re-implement a webapp that was originally implemented (by someone else) using Extjs.

The only things I like about Extjs are the uniform look of its widgets and the broad range of widgets it supports.  But I find Extjs too big to find my way around, and often slow.

I know that I probably can find a jQuery plugin for any widget I could want, but, from what I've seen, there is not much uniformity of appearance (let alone implementation) across these widgets.

For the app in question i need at least the following:

1. tabs

2. grids (with and without paging)

3. combo boxes

4. radio button sets

5. checkbox sets

6. container panels

...and a layout mechanism for arranging these GUI elements.

Is there a *visually uniform* suite of jQuery widgets that would provide all the above?

TIA!
