KDE_core and Webkit interface

Hi all !
I'm a Newbie and I have a team.
My team has the project. It builds interface base on KDE-core and Webkit. But we don't know the point we can start and how to combine KDE core and Webkit to one interface.
Please Give us some advice such as progamming language or support us when you're posible.
thank for reading and help us if you can
