Some stupid questions

[Another rookie]

Hi I'm an old fart and a newbie. So I hope you'll bear with me and answer a 
few basic questions for me. Feel free as patronizing as you want.

I've just downloaded the latest version of Python 2.2, and have started 
learning to program from the web tutorials. If I stick with it ......

... Will I be able to compile my progs as executables, so that they can run 
on anybodies machine, whether or not they have a version of Python 
installed?

... If not, does jpython or jython allow me to compile my progs as java 
apps, so that they will run on any machine with java?
