GTK doesn't really have maximum sizes. It probably should. 

Try playing with something like this:
  - use a GtkTable, with a GTK_SHRINK flag on the top text widget
    and GTK_EXPAND | GTK_FILL on the bottom one
  - set the size request of the top text widget to allow 5 lines,
    using gtk_widget_set_size_request() for now. Pass -1 for the width 
    request to leave it unaffected.

TextView is supposed to have a height_lines and width_columns
properties; however they aren't implemented yet, there's a FIXME in
the code. I just filed
http://bugzilla.gnome.org/show_bug.cgi?id=62103, you can track that
issue by putting yourself in the CC list.  These would set the size
request in terms of line height/column width.
