Hi Chip, you need to hide the widgets you don't want:

#include <gtk/gtk.h>

int
main( int argc, char **argv )
{
	GtkWidget *fsb;
	GtkWidget *but;

	GtkWidget *wid;

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

	fsb = gtk_file_selection_new( "" );

	gtk_widget_hide( GTK_FILE_SELECTION( fsb )->dir_list->parent );
	gtk_widget_hide( GTK_FILE_SELECTION( fsb )->history_pulldown );

	gtk_file_selection_hide_fileop_buttons( GTK_FILE_SELECTION( fsb ) );

	gtk_widget_show( fsb );

	gtk_main();

	return( 0 );
}

This isn't bulletproof though :-( for example, a user could type 
"../fred" and select a file in the parent directory.

You'll need to either also get rid of the text selection area and do 
that stuff yourself, or carefully sanity check the results of the dialog 
and pop and error box if you think the user is messing about.
