You need to be able to have good skills as a composer as well as a fair degree of creativity in order to make good music using only software. And you need to learn how to use the software, too. I've tried electronic music, and I honestly find it a lot easier to play a guitar or bass.
The quality of music isn't defined by how difficult it is to play, anyway. Coldplay, for example, is very, very simple music. Compositionally, a good lot of modern electronic music is more complex. That doesn't make it better, or worse. Joy Division, The Clash, Coldplay, Soundgarden, none of those bands make music that is ridiculously difficult to play. Look at The Beatles, none of them were particularly remarkable musicians. You know what is really hard to play, though? Brain Drill.
That's hard as hell man! Do you like that? What? Why not?
