Write a GUI application that converts Celsius temperatures to Fahrenheit temperatures. The user should be able to enter a Celsius temperature, click a button, and then see the equivalent Fahrenheit temperature. Use the following formula to make the conversion: F = 5/9 * C + 32 where F is the Fahrenheit temperature and C is the Celsius temperature. EXTRA CREDIT: Have a second button to do the reverse (i.e. calculate the Celsius, given the farenheit)
