This is beside the point.  Trees are isomorphic to lists that contain
lists.  For example:

winout << title("Example window")
       << divider(2) << up << ( panel << vertical 
                                      << label("Hello, world!")
                                      << textentry("Name: ") )
                     << down << ( panel << horizontal
                                        << button("OK")
                                        << button("Cancel") );

Which, assuming my parens are right, could give you something
like:

+---------------------------------------------+
|     Hello, world!                           |
|     Name: ____________________________      |
+---------------------------------------------+
|      /-------\         /--------\           |
|      |  OK   |         | Cancel |           |
|      \-------/         \--------/           |
+---------------------------------------------+

Best,
