I can't comment on PyQt5 but I can say how to use PyQt4 with virtualenv
on Windows.

The Riverbank installers do not work in a virtualenv. However PySide
wraps PyQt4 in a compatible installer. To use the installer it should be
invoked with easy_install rather than pip install. Having installed it,
pip uninstall works.

https://pypi.python.org/pypi/PySide

The Riverbank installer can install PyQt5 to your master copy of Python.
You can then use the --system-site-packages flag when creating a
virtualenv. The default behavior of virtualenv changed in 1.7
(2011-11-30) from including system packages to excluding them.
