PangoLayout *pl;
int width;

pl = pango_layout_new(gtk_widget_get_pango_context(widget));

pango_layout_set_text(pl, "sample text here", -1);
/* -1 indicates "use strlen() to find length of string. */
pango_layout_get_pixel_size(pl, &width, NULL);
/* NULL because we don't care about height. */

gtk_widget_set_size_request(widget, width, -1);
/* -1 because we don't care about height. */

/* make sure to unref the PangoLayout! */
g_object_unref(G_OBJECT(pl));


Lemme know if you have any problems...
