Not really...
Firstly, "creation" and "annihilation" have more sense in the second quantization language for many body systems, while both SHO and infinite well discussed here are single body problems.
Secondly, indeed you can use certain operator method for SHO, which looks like "creation"/"annihilation" operators. They actually have the meaning of "creation"/"annihilation" if you forget the oscillator but deem the ground state as certain vacuum and excited states as states with more "particles" carrying the same amount of energy.
Thirdly, the existence of operator method for SHO is associated with the fact that the energy spacing of arbitrary two adjacent states is a constant, which allows you to write the Hamiltonian as a linear function of $a^{\dagger}a$, i.e. $(H-H_0)\propto a^{\dagger}a$. And in practice, this is because the Hamiltonian of SHO in the 1-dim space is purely a second order one (in the operator sense) which allows you to do a square-decomposition, while an infinite well problem is not: the potential energy vanishes outside the well, which is a purely non-linear constraint. For sure, as Sal suggested, you may try a decomposition of a forth order (in the operator sense) Hamiltonian (we know that from the result of the infinite well problem), which is not easy at all -- to find the explicit form of the operator....
