An unusual question... this isn't easy folks!

OK People,

Hey for those of you who don't know me they call me JC, and I'm here with a question. I've been around, read all you guy's reviews, but this is my first time posting with an actual question instead of a comment. As you may or may not know I'm a musician, I've been playing piano/keyboard for about 7 years and been learning guitar, bass, and drums recently also. This sets the stage for my question. Tell me if this chart is possible.

So thats it. I have 5 instruments that I want to record simultaneously, and I need to convert each instrument cable into a PC input. So in short I need to know what hardware and what software to get. I'd appriciate any ideas you guys could give me. Thanks!
