Calculator GUI

Using the Windows calculator program as a model, develop a basic calculator program with a GUI, such that a user may perform the basic operations of addition, subtraction, multiplication, and division. The operations may be “atomic?? that is to say, only one operation at a time need be performed, so the user will ask for the sum of two numbers, and have to press the = key to get the result, they may not chain operations together before pressing =. However, the program should handle an illegal operation like division by 0. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
