Eryk Sun added the comment:

You can build NumPy with only a C compiler, but it won't have accelerated 
BLAS/LAPACK. However, lifetimes requires SciPy, which in turn requires Fortran. 
This is a common requirement with a lot of the scientific-computing stack, so 
you may as well choose a complete solution such as Anaconda.

That said, if you just need a few packages, then Christoph Gohlke provides an 
extensive collection of wheels [1]. For example, I have a directory with the 
following wheels downloaded from Christoph's site:

    C:\>dir /b Z:\Python\wheel
    matplotlib-1.5.0-cp35-none-win_amd64.whl
    numpy-1.10.2+mkl-cp35-none-win_amd64.whl
    pandas-0.17.1-cp35-none-win_amd64.whl
    scipy-0.16.1-cp35-none-win_amd64.whl

I'll test installing lifetimes and matplotlib in a virtual environment:

    C:\>py -3 -m venv --symlinks C:\Temp\env35
    C:\>C:\Temp\env35\Scripts\activate.bat

The command-line option "-f directory" makes pip look for packages in a local 
directory: 

    (env35) C:\>pip install -f Z:\Python\wheel lifetimes matplotlib
