is it posible

ace:Don't double post. Read teh rulez.

Sorry, but in that method, no...
If you had the source code for the program, you could modify it for PSP's controls and compile it and there you go!
But most programs, no...

Do you know of any good compilers?

Right now, the only one that coders use for distributed homebrew is the PSPTOOLCHAIN. You need a native linux runtime environment if you've got XP or a Linux based computer.
