Simple Movement Controller Question

Hello. I know most of the community is tired of almost identical Rookie Questions but I am desperate.
My only previous programming experience was with HTML and a few visual scripting programs.
I am new to programming in Unity and have little to no knowledge about C# or Java Script. I switched to Unity for my current project as Unity is the only Engine that provides good Ad Sense support.
I am currently struggling to make a simple controller script.
This is what I am trying to achieve:
Player Object moves opposite the direction of mouse when clicked .
That's it, that's all I want.
Any help at all is appreciated.
