The tree buffer is a library from CEDET project, widely used in ECB. Look at 
this screenshot, and you'll see tree buffers at the top of the frame:

I did it with org-babel. Install it, using this manual:

http://orgmode.org/worg/org-contrib/babel/intro.php

then you can try treir sample, that I rewrote in Perl:

* Prefix

Here we have the code, that is output in the beginning of the file

#+srcname: hello-world-prefix
#+begin_src perl
print "/-----------------------------------------------------------\\\n";
#+end_src

* Postfix

This code will be used at the end of the file.

#+srcname: hello-world-postfix
#+begin_src perl
  print "\-----------------------------------------------------------/";
#+end_src

* File body

This is the main code of the file.

#+srcname: hello-world
#+begin_src perl :tangle hello.pl
  <<hello-world-prefix>>
  print "|                       hello world                         |\n";
  <<hello-world-postfix>>
#+end_src

---------end sample---------------------
You can edit the code in an indirect buffer, using C-c '. Tangle it with 
(org-babel-tangle).

The first step will be understanding, how does the CEDET library tree-buffer.el 
work.
