You shouldn't 'assume' that everyone who gets involved with something is going to 'just know how' to do it, nor should you assume that every person is as capable as the next of 'just doing' something, but I suppose any of you could just load up Fruity Loops or SoundForge and spit out a full length tune in 1/2 an hour.
Not everyone has the same level of 'knack' for understanding coding and graphic software. That's why these forums provide a great place for each and every person to learn, providing the sarcasm and veiled ridicule is left out.
And lastly, until you know who you're talking to, or about, it might be a good idea to stand on the side of politeness because you never know what 'said' individual might be able to do for you one day.
Merry Xmas!
