You need to call gtk_main() every time you show a window, and gtk_main_quit() to exit gtk_main(). 

Something like this:

#include <stdio.h>
#include <gtk/gtk.h>

void
button_click( GtkWidget *button )
{
       /* This will make the gtk_main() which called us return.
        */
       gtk_main_quit();
}

GtkWidget *
make_window( int n )
{
       GtkWidget *window;
       GtkWidget *button;
       char label[256];

       window = gtk_window_new( GTK_WINDOW_TOPLEVEL );

       snprintf( label, 256, "Loop #%d", n );
       button = gtk_button_new_with_label( label );
       g_signal_connect( G_OBJECT( button ), "clicked",
               G_CALLBACK( button_click ), NULL );
       gtk_container_add( GTK_CONTAINER( window ), button );

       return( window );
}

int
main( int argc, char **argv )
{
       int i;

       gtk_set_locale();
       gtk_init( &argc, &argv );

       for( i = 0; i < 10; i++ ) {
               GtkWidget *window;

               window = make_window( i );
               gtk_widget_show_all( window );
               gtk_main();
               gtk_widget_destroy( window );
       }

       return( 0 );
}

Use timeouts and event handlers to spot key presses and the 5 sec thing you were asking about.
