Using andedebauchery's excellent answer as a guide, I adapted these steps to get pdftk installed on my Heroku Node.js app from my Windows machine in September, 2015. The main differences between his steps and mine are:

1. I had to update the URL for the github repository from https://github.com/millie/pdftk-source.git to https://github.com/SirRawlins/pdftk-source

2. I had to download BSDtar in order to extract the executable from the pdftk.tar.gz (I tried GnuWin32 tar.exe first and it didn't work because it doesn't handle .tar.gz files)

3. I had to use git update-index --add --chmod=+x pdftk to grant execute permission on the file once it got to the remote Linux environment

Hopefully this will help other Windows developers in the future!
