I suspect that you are doing this:

void somemethod()
{
  Gtk::Window mywindow
  mywindow.show();
} //mywindow is now deleted because it is out of scope

rather than this:

void somemethod()
{
  m_mywindow = new Gtk::Window(); 
  mywindow->show();
}

But if you show some simple code then people can tell you what you are
doing wrong. This is rather simple stuff.
