HELP how to fill a tile in a map with image and its nearby tiles overtime

Hello, I am relatively new in using corona sdk but has decent knowledge in programming with background in C/C++, Java, VB.NET,C# etc.

Anyways, I am trying to make a game where there’s a bird’s eye view type of map with certain areas (tiles) of the map that needs to be filled with trees (using a tree image to fill a specific tile and will fill nearby tiles overtime) 

Is my idea possible using MTE? or can you guys recommend other engines/libraries that will be useful for this project. 

Good day to you all!
