Here is a short sample code involving qtpy and pandas.

I can compile this code with default download from anaconda64 for windows and pycharm community edition, all downloaded on 2016-04-07:

[0] install Anaconda64 for windows without prior install of python. As time of writting, Anaconda by default will install both 3.4.3 and 3.5.1 environment. But that does not cause any grief for me in the following steps.
[1] cmd: pip install pyinstaller, pip install can detect Anaconda's python.
[2] revert package "setuptools" to 19.2. I did that in pycharm (Settings, Project:, Project Interpreter) [3] follow instructions how to use pyinstaller, everything from here should be google-able

Caveat: the result is a 200MB 3000+ files folder. If you just want a quick exe to do some small chores, stay away from big packages. Pandas is at its best in its scripting form.
