Hm, this somehow works, but is not perfect:

--8<---------------cut here---------------start------------->8---
(widget-create 'tree-widget
	       :node '(push-button :tag "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" :format "%[%t%]\n")
	       `(tree-widget
		 :tag ,(with-temp-buffer
			 (set-fill-column 50)
			 (insert "bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla")
			 (fill-paragraph)
			 (buffer-string)))
	       `(tree-widget
		 :tag ,(with-temp-buffer
			 (set-fill-column 60)
			 (insert "foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo")
			 (fill-paragraph)
			 (buffer-string)))
	       `(tree-widget
		 :tag ,(with-temp-buffer
			 (set-fill-column 70)
			 (insert "baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz baz")
			 (fill-paragraph)
			 (buffer-string))))
--8<---------------cut here---------------end--------------->8---

The problem is that only the first line has correct tree lines...

But maybe that's still a pointer into the right direction.
