Hopefully Easy Variable Question?

I have a set of 5 buttons named

sysAdmin1Btn
sysAdmin2Btn
sysAdmin3Btn
sysAdmin4Btn
sysAdmin5Btn

Is there a way to have a counter variable be put in place of the number and still be able to access the var?
Ex.

 
var count:int = 0;
for(var int:i = 0; i < 5; ++i)
{
   //I want to be able to access all the var's through this, maybe something like
   //this even though it does not work?
   sysAdmin{count+1}Btn.visible = false;
}
