Here's an example from a program I'm doing:

void
save_file_as_activate(void)
{   
  if (!run_filedialog("Save source file", &pref.lastfn, "*.pfc"))
    return;
  printf("Save file as: %s\n", pref.lastfn);
  src_bff_save_file(pref.lastfn);
}

This function is called from the 'Save as...' item in the menu-bar or
from a button, as you wish.

gboolean
run_filedialog(char *title, char **fn, char *filter)
{
  GtkWidget *fs = gtk_file_selection_new(title);
  GtkWidget *selbtn = GTK_FILE_SELECTION(fs)->ok_button;
  const char *p;
  int result;   

  if (*fn)
    gtk_file_selection_set_filename(GTK_FILE_SELECTION(fs), *fn);
  gtk_window_set_modal(GTK_WINDOW(fs), TRUE);

  result = gtk_dialog_run(GTK_DIALOG(fs));

  if (result == GTK_RESPONSE_OK) {
    p = gtk_file_selection_get_filename(GTK_FILE_SELECTION(fs));
    *fn = realloc(*fn, strlen(p)+1);
    strcpy(*fn, p);
  } else
    fn = NULL;

  gtk_widget_destroy(fs);
}

This is the function that does the dirty work of showing the file dialog,
running it, and destroying it. Note that the 'filter' parameter doesn't
work.
