 * @flags: from #GtkDialogFlags

 * @first_button_text: (allow-none): stock ID or text to go in first button, or %NULL

 * @Varargs: response ID for first button, then additional buttons, ending with %NULL

 *

 * Creates a new #GtkDialog with title @title (or %NULL for the default

 * title; see gtk_window_set_title()) and transient parent @parent (or

 * %NULL for none; see gtk_window_set_transient_for()). The @flags

 * argument can be used to make the dialog modal (#GTK_DIALOG_MODAL)

 * and/or to have it destroyed along with its transient parent

 * (#GTK_DIALOG_DESTROY_WITH_PARENT). After @flags, button

 * text/response ID pairs should be listed, with a %NULL pointer ending

 * the list. Button text can be either a stock ID such as

 * #GTK_STOCK_OK, or some arbitrary text. A response ID can be

 * any positive number, or one of the values in the #GtkResponseType

 * enumeration. If the user clicks one of these dialog buttons,

 * #GtkDialog will emit the #GtkDialog::response signal with the corresponding

 * response ID. If a #GtkDialog receives the #GtkWidget::delete-event signal, 

 * it will emit ::response with a response ID of #GTK_RESPONSE_DELETE_EVENT.

 * However, destroying a dialog does not emit the ::response signal;

 * so be careful relying on ::response when using the 

 * #GTK_DIALOG_DESTROY_WITH_PARENT flag. Buttons are from left to right,

 * so the first button in the list will be the leftmost button in the dialog.

 *

 * Here's a simple example:

 * |[

 *  GtkWidget *dialog = gtk_dialog_new_with_buttons ("My dialog",

 *                                                   main_app_window,

 *                                                   GTK_DIALOG_MODAL | GTK_DIALOG_DESTROY_WITH_PARENT,

 *                                                   GTK_STOCK_OK,

 *                                                   GTK_RESPONSE_ACCEPT,

 *                                                   GTK_STOCK_CANCEL,

 *                                                   GTK_RESPONSE_REJECT,

 *                                                   NULL);
