It a very simple convenience wrapper which selects a good precompiled 
toplevel with Gtk initialized.

You can get rid of it :
- for programs without threads, just start
     ocaml -I +lablgtk2 lablgtk.cma gtkInit.cmo

- with threads : 
    ocaml -I +threads -I +lablgtk2 unix.cma threads.cma lablgtk.cma 
gtkThread.cmo gtkInit.cmo gtkThInit.cmo

Replace lablgtk2 by lablgtk if you are a Gtk 1.* user.

This is not the same thing :-)
Moreover you may prefer to compile your programs instead of using an 
interactive toplevel.

ocamlc -I +lablgtk2 lablgtk.cma gtkInit.cmo

to produce portable bytecode or even

ocamlopt -I +lablgtk2 lablgtk.cmxa gtkInit.cmx
to produce native code.
