UIViews like this can be acheived using a B4i Class, attached is an example, it's not perfect but should get you going. I haven't styled the label or anything else particularly. It's setup for strings, you may have to change some of the types if you want floating point or other objects in there. I'm sure you could make it a universal solution, but I don't have the time right now. This is just an example, and a lot less work than wrapping a library.
I think it's unrealistic to expect non-native views (with the exception of a Custom View implementation) to be included in the B4i designer. I'm sure it could potentially cause all sorts of problems with licensing, maintenance etc.
