GTK_POLICY_NEVER sounds like a good idea. (I'll add it to the TODO
list). But, your desired behavior is actually very easy to obtain -

POLICY_XXX currently only refers to the CList and ScrolledWindow
widgets. The text widget currently does not have the capability to do
automatic scrollbars. So, simply don't create a horizontal scrollbar
for your Text widget.

[ Jay Painter has suggested in the future abstracting scrollbar
  capabilities out into a ScrolledWindow class that could hold
  not just Viewports, but also other scrollable widgets ]
