BPEL Designer outside netbeans

Hi,

I think the BPEL design view is a really neat visual authoring tool.
Great job to those involved ;-)

Can anyone give me a rough estimate of how much effort it would be to
use the BPEL editor outside of the netbeans framework.

I'm currently using the netbeans graph library in one of my projects
but I'm thinking of switching to the BPEL visual editor (if possible)
'cause it such a cool tool.

Thanks alot
Wynand
