My advice is to make a list of all the DAWs that appeal to you and test them out. One per week.
Week 1: FL Studio
Week 2: Ableton
Week 3: Logic Pro
Week 4: Reason
Week 5: Ableton
During each week, actually LEARN to get around the DAW. Watch tons of tutorials and read read read. If for example, you're halfway through a week and you know that the DAW is not for you, then move to another one. However, if you immediately fall in love with a DAW (like FL Studio ;) ) then stick with that one and learn even more about it.
If you want a personal recommendation, FL Studio has literally thousands of tutorials online and is very easy to use and learn. It has a very simple and fast workflow and seamlessly hosts 3rd party plugins. Don't let its simplicity fool you though---it's a super duper deep program. The amount of things you can do in it is outstanding. I've been using it for 2 years now (very consistently too) and I'm still learning new things every time I open it up.
Since you said you are looking to only create music using the computer, then FL Studio is for you. I feel like other DAWs like Reason and Logic Pro put more emphasis on the recording aspect of music production and it takes away from the workflow necessary for putting together an actual song.
Well good luck, and last but not least, keep on frequenting these forums. I wouldn't be where I'm at today if it weren't for the kind people here.
