But I think you're going to find yourself frustrated with Jabaco sooner than later.

It is a nice idea, but it will always be a second or third-class citizen in the Java ecosystem. It may be nice for some learning, teaching, introductory programming scenarios but I don't think it will ever be used much for anything but that and recreational programming. I don't mean it lacks potential, it just has an uphill journey to gaining any real acceptance.

Java guys want to write Java. .Net guys want to write C#. VB.Net guys are already pretty marginalized in the market.

Have you figured out yet how you would even package a Jabaco program to deploy it as freeware? What tools are there to help you bundle up a JVM and the necessary Jabaco libraries to let somebody run your program on a computer that doesn't have Jabaco installed for development?
