Use something like:

class CMyEdit : public CWindowImpl<CMyEdit, CEdit>
{
...
DECLARE_MSG_MAP(CMyEdit)
   MSG_WM_COPY(OnCopy)
   MSG_WM_PASTE(OnPaste)
END_MSG_MAP()
...

}

This is how you subclass a window in WTL.  CWindowImpl-derived classes do have a SubclassWindow function.

I would recommend going to www.codeproject.com and locating and reading the articles in the WTL for MFC Programmers series.  They are a very good introduction to WTL, subclassing controls, etc.
