* @first_button_text: 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 "response" signal with the corresponding
* response ID. If a #GtkDialog receives the "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:
* <informalexample><programlisting>
* 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);
* </programlisting></informalexample>
