Hi, the best thing to do is to copy and paste code from 
widget_portlet_navigation (navigation portlet) as you've started doing, 
then remove all references to datastructures (ds options/datastructure 
and other parameters that come the portlet's own schema). Then create a 
custom portlet with the page template.

Since custom portlets have no parameters, all parameters available in 
the navigation portlet will have to be hardcoded in the page template 
instead. However the page template can also get information from the 
current section, which is what it does in the code I sent.

then pass the information to:

items python: context.getFolderContents(....);

I think it's called 'sort_on'

that should do the trick.

the schema / layout that you should modify is the one of the "Section" 
type (there is no need to change the portlet's schema / layout)
