There's a bit in Sex and the City where Carrie gets broken up with on a post-it note.
Harsh, but as long as he doesn't see her again EVER he managed to avoid all the emotional ickiness that goes along with breaking up.
How else can you give someone the big E(lbow) without having to face unpleasantness?

Well this is coming from a girl's point of view so I'm guessing I might be a little different here...
I think that's really cowardly of you. If you're going to get into a relationship, you ought to realise that it comes with the responsibility of accepting a breakup honourably should she decide she doesn't want you anymore, and also of conducting a breakup honourably if you decide you don't want her anymore. To try to break up with someone without 'having to face the emotional ickiness' is childish. Obviously you don't care about how she would feel - which says you're not ready to be in a relationship in the first place.
Also consider the fact that any decent girl would respect you more for having done it the proper way, and is therefore much less likely to 'backblast' you than if you did something immature like breaking up via post-it notes. Do that and you're likely to be faced with a girl so angry at you for not even respecting her enough to do it face to face, that she'll get you back. Do it properly and you'll have given her the closure she needs and shown yourself to be firm in your decision and she may just leave you alone like you want.
Offer to meet up at her place and allow an hour. You don't need to tell her that necessarily but don't be too enthusiastic about it either. Just say you'd like to come over if that's okay. Then you can sit her down, explain that you're just not feeling it for her anymore and it's not working. It'd be mean to draw it out any longer or string her along so you've decided to end it. Don't offer to be friends if you don't want to, just leave it at that. Say you're sorry it's had to come to this but that's the decision you've made and you can't try to convince yourself otherwise. Be calm and firm, give her a moment, don't give her any 'reasons' for why you've broken up because she's likely to give you ways that she can fix them (for example, 'you never let me watch the football' is likely to be met with 'I'll let you watch it from now on' etc) just keep it at 'it's not working.' Don't kiss her, don't hug her, put a hand on her shoulder at most or just keep your distance. If she's not asking you any more questions, say you hope she can find someone better suited to her, say goodbye and leave. If she gets angry at you then repeat that it's the decision you've made and you're going to stick with it, say you hope she can find someone better suited to her, say goodbye and leave.
She's then in her own home and able to do what she needs to get over it, and you're free to do what you want. This way you've dealt with the emotional ickiness but it hasn't taken much time. It's an hour of your life compared with a lot of trouble you'd have had to go to in trying to avoid her later if you'd done it another way, plus you may even get a bad reputation among girls who know her as opposed to doing it respectfully.2
