How to make an outline of the inner parts of the letter "B" ?

[getsignups]

So I know how to make an outline on the outside of objects and text, but how do I do this in the inner areas of text?
For instance , take the letter "B".

Also, how do i remove this irritating "Tool options" tab from the left hand corner of Gimp? It's blocking things in that area of my screen.

Thanks!
