Yup it is, will digg up some examples

You can create a workflow like this

    [Workflow("Send Email",FormState.Submitted)]
    public class Email: WorkflowBase
    {

        public override WorkflowType Type
        {
            get
            {
                return new Umbraco.Forms.Core.Providers.WorkflowTypes.SendEmail
                    {
                        Email = "test@test.com",
                        Subject = "the form Contact Form was submitted",
                        Message = "the form Contact Form was submitted, " +
                                    "this is the list of values it contained, " +
                                    "you can turn this email off under workflows in Umbraco Contour"
                    };
            }
        }
    }

Then on the form class override Workflows property

        public override List<WorkflowBase> Workflows
        {
            get
            {
                return new List<WorkflowBase> {
                        new Email()
                    };
            }
        }
