For the crust, mix together graham cracker crumbs, melted butter and sugar, and pat into a 9 x 13-inch glass dish or 10-inch glass pie dish.

For the filling combine eggs, unsalted butter, confectioners' sugar and vanilla. Beat with electric beater for 20 minutes. Spread creamed mixture over cracker crust. Arrange bananas over top of mixture, then spread crushed pineapple over bananas. Cover with prepared Dream Whip. Sprinkle nuts on top; chill overnight, or at least 8 hours before serving.
