Tutorial: create a CSS box with rounded corners in Dreamweaver

I think in 99% of the cases, if you are a Dreamweaver user and deal with design implementations work starts by getting the layout from the designer and you are supposed to make the site code that replicates exactly the layout. And designers can be picky! Nowadays you are supposed to create table-free code using DIVs and CSS, which can be a headache sometimes, especially if the designer threw in some rounded corner boxes and containers. So basically you have to cut the design elements probably using Photoshop and handcode the DIVs, but is there a better way to do this?

What if you could do all this using just Dreamweaver and a Dreamweaver extension called FlexiPanels CSS? What if with the extension would lay out the CSS compliant code for the boxes and also help you cut the design?
