Help me make a GUI based application which converts Canadian dollars to other country's currency.

Description: Converted currency would be displayed in the screen when radio button is selected and then " Convert " button is clicked . After clicking Convert button , user should be able to see the conversion rate as well as shown in Fig 2 Your Code should also check for valid input in the TextField . If the input for Canadian currency is not valid , then it should display " Error " message as shown in Fig 3. You can either design the UI just as given in Fig: 1 , 2, and 3 or you can design your own UI. But your design should use nested layout and have all the information as given in Fig 1, 2, and 3, including image of Canadian flag and perform as specified .Below is the currency conversion table along with unicode for currency symbol. Currency conversion rate might not be up to date. You can use the current conversion rate if you want. Your UI should display the rate you are using.
