Hey - Start off by downloading and installing the Google Play Store APK here http://www.apkmirror.com/apk/google-inc/google-play-store/ - then try and launch it and let us know what you get. To remove the PlayApp, go to Settings > Apps > All > PlayApp > Uninstall > confirm... If you get any errors, then it will be that Google Play Services needs to be installed too. Comment below as you get along otherwise. Remember that you can auto login with your Gmail or Facebook account.
