Well I have finished writing the GUI for my calculator but I am now facing a bit of a dilema.
I cant seem to figure out how to get the number the user imputs and put it into a variable without using strings and I cant convert my strings to integers.

Would anybody be able to help regarding this?
I have declared a few variables that I thought I could use to solve this problem but it seems that I was wrong.
These variables are "x, y, temp and operand".

All I have to figure out is how to allow the user to input what they want by pressing the buttons and then passing it into an integer variable some how.

Here is my source so far.
