This last line is the problem.  ListBox widgets are box widgets, but 
Pile widgets may only contain flow widgets.

You could replace the line above with:
     box = urwid.Frame( body, header=title, footer=footer )

Frame widgets have one box widget in the middle and may have header and 
footer flow widgets on the top and bottom.

In your diagram you are also showing two columns.  To create columns you 
use the Columns widget.  Something like this would work:

left_list = [urwid.Text("blablab\nOther text\n\nAnother txt")]
left_col = urwid.ListBox( left_list )
right_list = [urwid.Text("Some widgets here:"),urwid.Edit("Edits","")]
right_col = urwid.ListBox( right_list )
body = urwid.Columns([ ('weight',1,left_col), ('weight',3,right_col) ])

This creates two seperate ListBox widgets, one using 1/4 of the 
available space and the other using 3/4.

Hope this helps!
