It is not easy, due to the fact that ethoxide, can't be made by the combination of sodium or potassium hydroxide and ethanol, as one does with base plus methanol to form methoxide. It can be done however via alternative ways of making the ethoxide:
K + EtOH ---> K(+) (-)OEt + 1/2 H2 KH + EtOH ---> K(+) (-)OEt + H2 (don't try this at home- wildly flammable materials involved) or for someone with good laboratory skills: combine EtOH (absolute) + KOH, then distill off 95% Ethanol/5% water azeotrope to remove water, shifting the equilibrium to form the ethoxide ion. The problem is that you remove a lot of ethanol to get a small amt of water out. (there are ways to recover absolute ethanol via a ternary azeotrope, but I seriously doubt if it is either cost or energy effective.
