zettwerk.ui has no dependencies to plone.app.jquerytools. This comes from Products.PloneFormGen. Pin it to 1.6.0 to make you buildout runs again by adding the following to your buildout.cfg:

[versions]
Products.PloneFormGen = 1.6.0

If you want to use PloneFormGen 1.7 on Plone 4.0, it clearly notes the extra dependency on its PyPi page at http://pypi.python.org/pypi/Products.PloneFormGen/1.7a2 in the "1.7 Notes" paragraph.
