You can't do that, or anything similar. Admin side is very different from front end, and you can't just mix them. There is no plugin that can help you, or theme that already has that implemented, because it can't be done. The only way to do it is to write it from scratch, and code everything needed from back end into front end, and that is very, very complicated to do. TDO MiniForms plugin can be used to add new post into front end, but it's very limited compared to real back end and implements only some of the post features.

The other route that you were going down is far more doable than this one, I'm afraid. Short of tearing the whole admin template system apart and redoing it, you can't reuse the fronted components on the backend - wordpress is just too single-mindedly built for that, not modular at all. The suggestions made in the other thread were actually pretty good. What you're asking for is something that requires a *very* significant change to the base behavior, so getting familiar with the intimacies of plugins & templates is a must. No offense, but if that other stuff was over your head, you might need to hire someone to do it for you - and that's a lot more than $8 worth of work. ;)
