I want to develop a one Mathematica application with GUIKit.
I need for my application a Widget "Tree". But there is almost no
documentation by Mathematica for this Widget.
How can I add/remove a new node to/from a Tree?

I gave up on GUIKit long ago because of its bugs/quirks and lack of
documentation. I wrote the Super Widget Package (SWP) (available free
from my site) that offers more extensive facilities with documentation!
Additionally, the SWP requires essentially no knowledge of Java.

Of course, since 6.0 you can make GUI's inside notebooks, so you need to
think if you need the standard look and feel that Java (which GUIKit and
my SWP both access to produce the GUI) can bring, or if a notebook GUI
would be acceptable.
