Sorry to disagree with your first sentence, Constantine.
Logistic regression stipulates a linear relationship of covariates with the log of the odds of an event (not odds ratios). From this it is straightforward to recover the probability (or risk, if you prefer that label) of the event.
Don't understand your aversion to logistic regression to achieve what you want to achieve.
If you don't like the shape of the logistic, then any other cdf will provide you with a transformation to obey the constraints inherent in modeling a probability. The uniform distribution that you wish to use has to be curtailed, as others have pointed out.

No argument about logistic regression. But that gives you odds ratios. What if you want risk differences instead?
