you can write that in python or with page templates.

see for instance
http://cvs.nuxeo.org/cgi-bin/viewcvs.cgi/CPS3/CPSSkins/skins/CPSSkins/cpsskins_main_template_default.pt?rev=1.30&content-type=text/vnd.viewcvs-markup

ideally it should be enough to call a layout.render() that recursively 
goes through the entire tree, that when it finds a node renders some 
"container" markup in the destination language (e.g. <table>, <div>, 
...) and when it finds a leaf renders the object (portlet, box, 
document, ...)

Unfortunately this cannot be done with ZPT macros since a macro slot is 
only one side of a coin (every 'define-slot' requires a 'fill-slot').  I 
see it as a huge step backwards in terms of modularity. Good for 
GoLive/DreamWeaver web designers in Zope, but not for product designers.
