Design tools for skinning Flex 4 components
Flash Catalyst should be like this.
however - imho - it is rather difficult to use it in a practical environment where there is a workflow like
design> dev> design update> dev> design update> dev
as Flash Catalyst really only works one way.
It's a nice try from Adobe, but it's not quite yet.
You can use it, however, to cut the design yourself, export the result to a separate project, and import it into your current flex project.
Get a trial and see for yourself.
I don't know of any other "tool". You can export your graphics from a design document and import them manually as assets otherwise .. but it gets tiresome quickly.
I would be interested to know if anyone has a better solution.

Check out the new version of Flash Catalyst Panini from Adobe Labs. It has a round trip and allows you to use your own component from Flash Builder. Also look for the Flash Catalyst Jailbreak post as it will show you how easy it is to work between Flash Builder and Flash Catalyst.
