Most of not all computers can support making music.
Equipment is just literally your computer, man! Unless you're wanting to go serious, just rely on your regular keyboard as most DAWs will use that for default if you don't have a MIDI controller at hand.
FL Studio is a good, easy program. It's what I use, and there's alot of good tutorials on how to use it for electronic music. If you feel like a big pro at some point, you can upgrade to Ableton if you want.
Watch a ton of tutorials and actually play around in FL Studio for a bit. Get the feel of it, and learn how music works.
