Bad move, it will segfault if you put into the entry 26+ characters.

void
on_button1_clicked(GtkButton *button, gpointer user_data)
{
  gchar *output;
  GError *error = NULL;
  GtkWidget *label = lookup_widget(GTK_WIDGET(button), "label1");
  GtkWidget *entry = lookup_widget(GTK_WIDGET(button), "entry1");
  const gchar *url = "http://website.com/path";;

  if( entry ){
    output = g_strdup_printf("%s %s=%s",
                             BROWSER,
                             url,
                             gtk_entry_get_text(GTK_ENTRY(entry))
                            );
    g_spawn_command_line_async (output, &error);
    if( error ){
      g_print( "Error: %s\n", error->message );
      g_error_free(error);
    }
  }
}
