Columns is the best widget for what you're looking for.  If the text on 
the right or left is a fixed length then you can do something like:

header_widget = urwid.Columns([('fixed',10,left_widget), right_widget])

This way all the rest of the available width will be allocated to 
right_widget.

The only way to make right_widget appear on the right side at the moment 
is to use right-aligned text like:

right_widget = urwid.Text("I'm in the top right corner!", align="right")

In a future release I am planning to modify the Columns widget so that 
it can do right-alignment by detecting the width of the widgets it 
contains.. see: http://excess.org/urwid/ticket/11
