(A county collects property taxes on the assessment value of property, which is 40 percent of the propertys actual value. If an acre of land is valued at $10,000, its assessment value is $4,000. The property tax is then $0.64 for each $100 of the assessment value. The tax for the acre assessed at $4,000 will be $25.60. Create a GUI application that displays the assessment value and property tax when a user enters the actual value of a property. The window should be similar to the one displayed above.)

(I've been trying to find ways to have the two buttons placed on the bottom left of the GUI application, but haven't been having any luck. I hope the additional instructions make it clear enough.)
