Glade provides a lookup_widget() function to get a pointer to any widget
in the same window. So you could use:
void
on_ok_button1_clicked (GtkButton *button,
gpointer user_data)
{
GtkWidget *entry1, *entry2;
entry1 = lookup_widget (GTK_WIDGET (button), "entry1");
entry2 = lookup_widget (GTK_WIDGET (button), "entry2");
...
assuming your widgets are named "entry1" and "entry2".
