Help!

OK, I need some boy help. Not help WITH a boy, help BY a boy. Or, even just someone who is more "handy" that I am, which honestly, could be a 4-year old girl or maybe even an orangutan.

So, I got new cabinet knobs for my kitchen. They're pretty sweet. They look like this:

I installed most of them ALL BY MYSELF, using my new girlie power drill and I think, if I may say so, I did a pretty nice job.

So, they have a long screw, (or bolt? not sure of the correct terminology) that doesn't have a hole in the head, and it goes through the knob and has a nut on the back side, like this:

The old knobs had regular Phillips heads that screwed into the knob itself on the other side of the cabinet door. Well, I also got knobs for the doors to my kitchen but I just realized that the knobs on the doors are double-sided, so they screw into each other, like this:

So, my question is, how can I install the red knobs onto my doors, since they don't actually screw themselves, but need a nut??

Just for the record, I am not fond of home improvement. Although I did install a towel rod in the bathroom yesterday. And similar cabinet knobs in coke-bottle green. This is just not a hobby I can get behind.

Can anyone help a damsel in distress??
