It seems that widget-create does not recognize :expander. Please examine
this:

(progn
  (require 'tree-widget)
  (widget-create 'tree-widget
                 :tag "blah"
                 :expander '(lambda (x) '((tree-widget :tag "x")))
                 :expander-p (lambda (&rest ignore) t)
                 :open t))

You should see                 

[-] blah
 `-[+] x          

but I guess you don't
