I don't understand your problem.  For instance, I have this as my
main function:

int
gui_back_end_main_default (void)
{
  initialize_main_loop ();

  gtk_control_center_present ();

  run_main_loop ();

  return 0;
}

Essentially, gtk_control_center_present() creates one instance of main
window and calls gtk_window_present() on it, and run_main_loop() calls
gtk_main().  So, if I wanted to open a file chooser, I'd just make it
look like

  ...
  gtk_control_center_present ();
  create_a_file_chooser ();

  run_main_loop ();
  ...

What's wrong with this?
