The Intel versions cannot run an PowerPC Macs. The PowerPC versions can run on an Intel Mac because of "Rosetta"; it's built into the Intel versions of OS X and translates PowerPC code to the Intel instruction set. There is no such thing on PowerPC OS X for Intel code, though.
I had the editor running on my PowerBook G4, and it seemed ok (since I don't know what it does or how to use it, but the editor window was there with icons and all and I could type text). The "runtime" program disappeared immediately after I double clicked it; jumping icon in dock, then gone. But I don't know how to use that one either, so maybe that's what it should do when you don't do anything else with it?
But maybe you have one of the classical endian problems in your code which causes the program to crash; PowerPC CPUs use a different byte order than Intel processors.
