Hmm... if I look at the winhelp there are only 6 more :-) 
But some of them you can't put them in the class.
  GWL_EXSTYLE, GWL_STYLE 
    can
  GWL_WNDPROC	, DWL_DLGPROC
    this one is incompatible with the windowproc we use 
    (that's an object instance pointer this is a pointer)
  GWL_HINSTANCE
    depends on application and doesn't have to be stored 
    in the class
  GWL_HWNDPARENT
    obvious
  GWL_ID
    ?? the gtkwidget as ID ??
  GWL_USERDATA, DWL_USER
     this is userdata and I think you want to store this 
     in the class 

  DWL_MSGRESULT
    ??

seen this I think it makes not a big difference of storing them all, you
have to store some of them anyhow. Besides that GetWindowLong is an API
function and I think that it is not a good thing to mess up the LCL with
these.
