Is it possible to create an android application that acts on the principle of modernized parental control?

Question

Android

Many people know that there is an application M-spy, which works mainly on the android platform for mobile phones. Roughly speaking, this application for a kind of parental control and similar applications are installed (for a good amount), most often, by serious companies on the smartphones of their employees (whatever tough conditions they come up with). The application shows everything that is produced on the smartphone itself.
So, is it possible to create a program that adjusts system protocols (for example, sip) and gives, for example, only one button on the smartphone screen, blocking access to all other functionality.
Situation in life:
Let's take an employee of some federal organization (just as an example) - he was given a smartphone. And with this smartphone, it can receive incoming calls and short messages through a large button in the middle of the screen that notifies you of an incoming message or call. Actually, she clicks on it and receives a call or message.
Is it possible to do this with an application written in a high-level language?
