Javascript hacks

I’m working on The Human Network project right now. The page was designed by a graphic design company, S3Group is contracted to implement the design to a working website.
The design looks good, but it’s a nightmare to implement, lots of rounded edges which mean lots of tweaking and adjusting. One problem that gives me headche is rounded edges rollover bar. There are three sections of the bar, the customer wants to be able to create new bar by adding text themselves, thus the content in the middle must be editable (can’t do with simple bar with text image). If no rollover simple div with background.
