Learning code should be the only way to make programming 'more accessible'. Black, white, yellow, red, gay, straight, whatever. None of that should matter. All that matters is that you can pull your weight.
There are fun statistics such as that women who are not immediately recognizable as such have a higher pull request acceptance rate on github than their male counterparts, whereas women who are easily identifiable have a lower one.
You can even be an open-source developer of one by starting your own project.
Maybe that tells you something about the general interest in programming by women. If people aren't volunteering, maybe they just aren't interested in that thing?
