// instruction

Create a GUI for your Agile or Waterfall program . Add these components to AgileWaterfallGUI.form. Again, use these names. **JTextField projectName** **JSlider peopleOnTeam** This should take values between 1 and 300. Add JLabels with the text "1" at the start, and "300" at the end, to indicate the start and end values. **JCheckBox firmDeadlines** **JCheckBox experienceAllPhases** **JCheckBox qualityControl** **JCheckBox earlyIntegration** **JCheckBox earlyWorkingModels** **JButton recommendMethodology** **JLabel recommendation**  Add more JLabels as appropriate, for example, to label the JTextField and JSlider name and max and min values. Your program can re-use the agileOrWaterfall method you wrote in Lab 3. Add a click event listener to the `recommendMethodology` button. When clicked, this button will read the data entered, and recommend Waterfall or Agile or Either for a development method for the project. Display the recommendation in the `recommendation` JLabel. Use the provided Strings `AGILE`, `WATERFALL` and `EITHER` and `RECOMMENDATION_TEMPLATE` to display the result. Your GUI program should use a JLabel and the recommendationTemplate format String provided to display something like Big IBM Project could use Waterfall or My assignment could use Agile or "Banking App could use either"
