The variational principle (VP) has been used to capture the metastable states of a glass-forming molecular system without quenched disorder. It has been shown that VP naturally leads to a self-consistent random field Ginzburg-Landau model (RFGLM). In the framework of one-step replica symmetry breaking (1-RSB) the general solution of RFGLM is discussed in the vicinity of the spinodal temperature T_{A} in terms of ``hidden'' formfactors $\tilde g(k)$, g_{0}(k) and $\Delta(k)$. The self-generated disorder spontaneously arises. It is argued that at T < T_{A} the activated dynamics is dominant.
