Using pd.MultiIndex.from_tuples may be more straightforward.

import pandas as pd
ind = pd.MultiIndex.from_tuples([], names=(u'one', u'two', u'three'))
df = pd.DataFrame(columns=['alpha', 'beta'], index=ind)
df.loc[('apple','banana','cherry'), :] = [4, 3]
df

one     two     three       
apple   banana  cherry    4    3
