Yay!  Thanks, finally got it -- and there's no need for the multiple
"X"s:

gint get_char_width (GtkWidget *widget)
{
    PangoLayout *pl;
    PangoContext *pc;
    GtkRcStyle *style;
    int width;

    pc = gtk_widget_create_pango_context(widget);
    style = gtk_widget_get_modifier_style(widget);
    pango_context_set_font_description(pc, style->font_desc);

    pl = pango_layout_new(pc);
    pango_layout_set_text(pl, "X", 1);
    pango_layout_get_pixel_size(pl, &width, NULL);

    g_object_unref(G_OBJECT(pl));
    g_object_unref(G_OBJECT(pc));

    return width;
}
