Mounting brakes (front and rear)?

I'm about to mount my engine kit and it strikes me how the heck am I going to install brakes on this thing when the place of the left brake lever will be taken up by the clutch lever? Other than putting two levers on the left side (clutch and brake) which I think will look cluttered/crowded and a bit goofy not to mention that the clutch lever will make it awkward to operate the brake lever.

do you guys have front and rear brakes on your bikes and how did you accomplish it? Do I have to be stuck with having only one brake? And if so which wheel should I choose, front or back? In my opinion I should probably choose the front since when you apply the brakes most of your weight shifts to the front and just like in cars the front wheels do most of the braking.

The problem is that I don't really want to trust just two tiny front brake pads with my life.

I thought about constructing some mechanism that would apply both front and rear brakes with just the one brake lever but then with my work schedule that will set me back a few weeks and I want to ride before winter is here. LOL Also there is the bigger problem of setting up the brake balance which is easily done with proportioning valves on the hydraulic brake systems of cars but with cables it might be a bit of a dilemma. Obviously you don't want the rear wheel skidding out from under you because the rear brakes grab first and harder than the front brakes.

Any ideas?

Thanks for all the the info guys. I think I'll have to purchase one of the dual cable levers. I don't want to rely on one wheel braking that's for sure especially since I'm thinking of using my bike for commuting to and from work, even in the wet. Don't want to rely on one brake on a cold wet morning.
