A89: Cabri Geometry Clone?

I am not a very good calculator programmer, but there are a lot of you out there, who are very good with assembly and calculators in general.

I was wondering...Is it that hard to write a freeware Cabri Geometry Clone, (something similiar), because it is a great program, but I wouldn't pay

more than 4.99 for a calculator program.. And it requires AMS 2.03, which is annoying.

Any suggestions? Maybe we should start a team on creating something similiar?

Thanx for input.
