First, good job on making a very reasonable SSCCE.

Second, the trick to Java's scoping rules is to change the rules!

Move the string strng1 from inside the actionPerformed to outside, right 
below the CalcGUIQ1 gui; line.  Now Java's scoping rules help you rather 
than hinder you.

BTW, this looks like a homework problem, and it looks like you've been 
getting help on it.  Some if it is a bit sophisticated for someone who 
doesn't understand scoping.  Please try to talk to your instructor or a 
TA, they need to understand when you're having problems with your lessons.
