Groovy Scripting
Groovy documentation can be found here Note, however, the documentation does not include much on building a GUI using SwingBuilder a better source is github.com/apache/groovy-examples
To see a demo of a Groovy GUI, based on the swing example from the above link, copy the code below and paste it into the System console, choose Groovy and then evaluate. It may take a few seconds for the GUI to appear. Use this code as

From josh-in-antarctica.blogspot.com A nicer way to do it using Groovy's with keyword: from
buttonGroup().with {
add radioButton(text: 'Option 1')
add radioButton(text: 'Option 2')
}
Spinners take the form of
spinner (id:'spinnerName', model:spinnerNumberModel(minimum:0, maximum: 40, value:20, stepSize:5)) spinner(id:'spinnerName', model:spinnerListModel( list: ["Text one", "two", "three", "four", "five"], value: "three") spinner(id:'spinnerName', model:spinnerDateModel(calendarField: Calendar.HOUR_OF_DAY)
