It's just too boring to create another platform independent GUI toolkit.
What about to extend lablgtk through camlp4 quotations so that
something like the following line is possible:

let window = << Button ~label:"Quit" ~callback:GMain.Main.quit >>

(equivalent to Tcl/Tk code:
pack [button .b -text Quit -command quit])


or

let editor_window = 
    << VBox 
        [Menu ["File" ["Open" ~callback:open; 
                       "Save" ~callback:save]; 
                        "Help" ["About" ~callback:about]];
         text = Text ~width:80 ~height:24;
         HBox [Button ~label:"Open" ~callback:open; 
               Button ~label:quit ~callback:Main.quit]] >>
                         
The Camlp4 had to 
  * create implizit the window widget
  * generate unused symbols (like the button name)
    but export the widget "text"
  * generate packing (vbox#add) 

Such code is better to maintain and it needs less time
to write. What do you think?

Christoph
