You write you want to generate random numbers with specified mean and variance.
Mean and variance are functions of alpha and beta:
So solve these relations E[X]=f(alpha,beta), Var[X]=g(alpha,beta) for alpha and beta.

The difficulty with the above is that Wikipedia only deals with the case of x ~ [0, 1] or x ~ (0,1) rather than a more generalized range.
