Answer 1

Instead of using Gtk.Window you can use Gtk.Dialog and use this code.

ResponseType response = ResponseType.None;
using (var dlg = new YesNoDialog ("Title", "Question", "Yes Button", "No Button"))
    response = (ResponseType) dialog.Run ();

if (response == ResponseType.Yes)
        OverwriteFile ();

Answer 2

It looks like you are trying to use System.Windows.Forms.Form.ShowDialog() in a Gtk# application.

The equivalent Gtk# function is called Gtk.Dialog.Run, see Is there a Form.Showdialog equivalent for Gtk# Windows?

You also need to create a Dialog, not a Form - ie. when you add the new class in MonoDevelop, you choose "Gtk / Dialog", not "Gtk / Widget".
