either write your own GnomeCanvasGridItem, or accept that a
GnomeCanvasLineItem is a rather small object and just use several of
them. 

of course, if you need a grid of several thousand lines, then a custom
canvas item is probably the best thing to do. canvas items are really
easy to write, perhaps an order of magnitude easier than a new
GtkWidget. The two online books listed on www.gtk.org explain how to
do this very well. I've written several new Canvas items based on
their explanations.
