Why not use Python, python has more mathematical modules like numpy as well as better compatibility with the UNO bridge.
Also you can generate Python extensions, so the code could be monetized. Also Python is much better supported and you can find tons of examples to do a lot in OpenOffice and Python (http://forum.openoffice.org/en/forum/viewforum.php?f=45), things like object analysis through MRI (http://extensions.openoffice.org/en/search/node/MRI). Also you have a third choice which is Java and also includes a very powerful support for creating components, and Calc Add-Ins which you can see some tutorials that work with NetBeans (http://wiki.openoffice.org/wiki/OpenOffice_Calc_Add-In_Project_Type).
