If you just want to “experiment” with software, then start with REAPER. It is a relatively simple “free” DAW which will cover all of your needs and will give you enough to make your tracks.
You can learn more about REAPER here: http://www.reaper.fm/
If you’re still set on Ableton (which is a great software, I use it too!), then I recommend you buy a MIDI controller that comes bundled with Ableton Live Lite. That will give you a taste of Ableton, and even if you don’t like it, you can still use it in your current setup. Unless you are using Serato DJ.
Here are some MIDI controllers that are good for DJing and come with Ableton Live Lite.
