KDevelop's UI - How Difficult to Extract for Own Program?

[jsmith435 at cox.net]

Hello:

I like your UI where you have the buttons at the bottom and sides that when 
clicked open small windows to do various things.  This concept is I think 
perfect for another application I'm currently designing.

My questions is this a standard widget of sorts, or is KDevelop's UI home 
grown by you all?  If so, in your minds, how difficult would it be to extract 
the UI code and bring it into a new application?

Thanks!
