Star Office 5.2 Schedule

[techclerk]

I saw the Schedule program of the older release of Star Office. I like how the interface appears similar to a Franklin Planner.
I visualize using this as a highly customized application for the small manufacturing business, but I'm thinking of it in terms of a Tetris style sorting game.
A company's standard product line can be found as objects in a folder that is a library of all products. When selected, they enter the Schedule environment, and that will drive production in real time.
I thought it might be possible to write macro objects that could self sort and fit into available Schedule time slots in order of priority and custom rule sets that reflect the real world systems of the manufacturing plant.
I think Star Office Schedule may have been let go, and perhaps JAVA would be a better than learning how to write macros for a discontinued product.
What environment would be best for a novice who is trying to do something like this? If I'm going to work on this during my own free time, I don't want to start behind the curve and I want to take advantage of groundwork that has already been covered.

99% of topics on this site are over my head. I have no training, certification, or help from anyone else at this time. I expect to only find an hour a day for working on this, and it could take me a year for the simplest demo to work properly.

If anyone has insight or guidance for me, please let me know what you think.
