The Lumia line of phones is not able to use programs from the Google store. There is a store application on the device to access the Microsoft store.

To elaborate on the answer you received from chancemeagre, the reason you can't install apps from the Google Play store is because your phone runs a version of Windows, not Android.
The Google Play store only has apps that run on phones using the Android operating system.
