Sure you can explicitly set the width of the cells you add to your
treeview columns:

http://library.gnome.org/devel/gtk/stable/GtkCellRenderer.html#GtkCellRenderer--width

For this you should use set expand to TRUE for the renderers you
are adding to that column with gtk_tree_view_column_pack_start():
