Keeping in mind the possible weak areas of the neck, wrists and lower back, and that you might want to work most of your body in one sitting, I might try something like these exercises if I were in your shoes. With all of these exercises, if you don't have access to watching yourself in a mirror for correct technique, you might want your husband, friend, or local fitness expert watch you try these exercises to help ensure proper technique.
1) Dumbbell Deadlift

*If you focus on keeping your back correct and straight, this "shouldn't" hurt your back. This works Back, Butt/Hips, Legs, and Thighs. Need I say more? Your husband will be drooling in no time.
It is a great compound exercise that is probably in line with Primal Blueprint theory. *
2) Some type of "rows" and/or pullups/chinups. Below are some rows. I prefer "A", which might be able to be modified for doing at home without a bench. "B" and "C" are two variations of the same thing (see hand position). B & C would work but technique would be critical for not hurting your lower back.

* I think a pull-up bar is a terrific investment.*
3) Seated dumbbell presses

4) Pushups - get some push up "handles" - probably the stationary ones versus "The Perfect Push-up" ones. This will help with wrist problems.
Anyway, the above exercises will pretty much work every basic muscle group and probably kick all the right hormones into gear for feeling and looking good - inside and out.
If you notice, the above exercises will also work your biceps and triceps in your arms, thus you wouldn't "have" to do any focus exercises for your arms unless you felt like adding them in later on.
I think the key to staying motivated with any routine that you try to make on your own is that you need to chart your progress. Either add more weight, more repetitions, or maybe even more sets - every once in awhile. Keep a spreadsheet and print it off, put it in a 3 ring binder, and chart your progress. (I could always show you an example of a sheet I've created and used in the past). Of course, take "before" and "progress" photos for even more motivation.
If you wanted to keep the routine even more simple, pick only a couple of the above to do for a few weeks, then switch it up with some of the other exercises for the next couple of weeks.
