You could probably use a post-install (postInst) user hook to do it,
but that can get a little hairy.  (I'm not certain what modules you
can reasonably use from code invoked via Setup.hs, and you'll have to
worry about tracking down/detecting/creating a public_html directory)
To use user hooks with cabal-install, you will also have to set the
build-type to Custom.

The list of user hooks is here:

Ed Yang has a blog post that discusses using user hooks to do
relatively complex build tasks.  While the context and objective are a
bit different, his examples may help to understand the syntax and
interactions between the cabal file and Setup.hs:
