Find a copy of the .apk file for the Play store.
Connect your device to your pc, then copy said .apk file to your device.
Find the file in ES file explorer, click it, allow it to install.
You may need to go into your settings and allow installation of non-market source apps. I'm not familiar with the kindle operating system, however.
