I'm a newbie too but here's what I did:

Implement the interface DecisionHandler and implement the 'decide' method which returns the appropriate transition.

public class MyDecisionHandler implements DecisionHandler {

	/**
	 * Comment for serialVersionUID
	 */
	private static final long serialVersionUID = 1L;

	
	
	public String decide(ExecutionContext executionContext) throws Exception {
		String lower = (String) executionContext.getContextInstance().getVariable("lower");
		String upper = (String) executionContext.getContextInstance().getVariable("upper");
		
		if ((Integer.parseInt(upper) - Integer.parseInt(lower)) > 10) {
			return "yes";
		}
		else {
			return "no";
		}

	}


Currently you can't use the GPD to associate the handler to the decision node, so you have to edit the process definition XML by hand like this:
