This reference from C++ wxWidgets and a few others seem to suggest a 
HWND window identifier can be linked to a Wx::Window using the
AssociateHandle method call:
http://www.wxwidgets.org/wiki/index.php/WxWidgets_For_MFC_Programmers#Associating_HWNDs_with_wxWindow_instances

However, although the AssociateHandle call is listed in the headers, 
it's not listed in the wxWidgets documentation. So at present it's not 
available in wxRuby. I will see if it's possible to add this call for 
the next release.
