Even if you're bad at coding, it's a good idea to read the manuals first.

First answer: Yes. Definitely possible. Dave's suggestion of using a trigger is definitely a good idea, though you could also set a distance. Here's a snip of code from a label that fades in and out based on the distance you are from it, and rotates to face the camera. Read through it a bit and then rework it for what you need if you'd like:

 //Set the distance at which the object fades, and how far it takes.
 var FadeStart : int = 150;
 var FadeDist : int = 5;
 
 //Which items should fade?
 var Panel : GameObject;
 var TextBox : GameObject;
 
 private var FadeEnd : int;
 
 
 function Update () {
 
 
 //Check the distance between the active camera and the text
 var dist = Vector3.Distance(Camera.main.transform.position, transform.position);
 FadeEnd = FadeStart+FadeDist;
 
 
 //Rotate the text to face the camera, as long as you're more than 5m away
     if(Panel.renderer.isVisible){
         if(dist>5){
             transform.LookAt(Camera.main.transform);
             transform.eulerAngles.x = 0;
             }
             
     //Fade the text and box, with an alpha between 0 and .75            
         if(dist>FadeStart && dist<FadeEnd){
             var renderAlpha = 1-(dist-FadeStart+(.4*FadeDist))/FadeDist;
             Panel.renderer.material.color.a = renderAlpha;
             TextBox.renderer.material.color.a = renderAlpha;
             Debug.Log(renderAlpha);
             }
         if(dist>=FadeEnd){
             Panel.renderer.material.color.a = 0;
             TextBox.renderer.material.color.a = 0;
             }
         if(dist<=FadeStart){
             Panel.renderer.material.color.a = 0.75;
             TextBox.renderer.material.color.a = 0.75;
             }            
     }
 }
