There are some options to try, but some may need to be run in an expose event callback
gtk_widget_grab_focus(widget)
gtk_window_set_focus (window, NULL);  

??? YMMV, and I'm still learning myself. :-)

I found that searching thru the maillist archives has many of these questions
answered already....you can download the tarballs of each month and search for 
previous solutions.

This will keep focus on the first window, but it's kind of an "negative soluion"
by denying focus to other windows. 

#include <gtk/gtk.h>

void destroy(GtkWidget *widget, gpointer data)
{
        gtk_main_quit();
}

int main(int argc, char *argv[])
{
        GtkWidget *window;
        GtkWidget *window1;
        GtkWidget *button;
        GtkWidget *button1;
        
        gtk_init(&argc, &argv);
        window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
        g_signal_connect (G_OBJECT (window), "destroy", G_CALLBACK(destroy), 1);

        gtk_container_set_border_width(GTK_CONTAINER (window), 10);
        button = gtk_button_new_with_label ("Some Button");
        gtk_container_add(GTK_CONTAINER(window), button);
        gtk_widget_show(button);
        gtk_widget_show (window);

        window1 = gtk_window_new(GTK_WINDOW_TOPLEVEL);
        gtk_container_set_border_width(GTK_CONTAINER (window1), 10);
        button1 = gtk_button_new_with_label ("Another Button");
        gtk_container_add(GTK_CONTAINER(window1), button1);
        gtk_widget_show(button1);
        gtk_widget_show (window1);

        /* comment out this line and window1 gets automatic focus */    
        gtk_window_set_accept_focus(GTK_WINDOW(window1), FALSE);
        
        gtk_main ();
        return 0; 
}
