This is easy since whe have a model/view relationship the view doesn't
hold any "real" information.  Just use
   
void gtk_tree_view_set_model         (GtkTreeView *tree_view,
                                      GtkTreeModel *model);

This will unset the current model and set the new one.  If you just want
to unset the current model then send in a NULL for the model.  Make sure
you have a refrence to the model if you wish to reuse it.  The models
must have identical metadata (i.e. # of columns and column data types).

Use a widget like the tabbed pane widget. There might also be a card
widget that stacks panes on top of each other without using tabs but I
could just be getting my GUI libraries mixed up.  Either way there is a
widget that does this.  Check out www.gtk.org and look at the API
documentation.
