In a small bowl, combine flour and nuts. Cut in butter until mixture resembles coarse crumbs. Press into a greased 13-in. x 9-in. baking dish. Bake at 300° for 25-30 minutes or until set; cool completely on a wire rack.
For filling, in a small bowl, cream the butter, cream cheese, confectioners' sugar and vanilla until light and fluffy. Spread over crust; cover and chill.
For glaze, 2-3 hours before serving, combine sugar and cornstarch in a small saucepan. Stir in water until smooth. Bring to a boil; cook and stir for 1-2 minutes or until thickened and bubbly. Remove from the heat; stir in gelatin until dissolved. Stir in lemon juice. Cool to lukewarm, stirring occasionally.
Meanwhile, arrange strawberries over filling. Spoon glaze over berries. Chill until serving. Garnish with whipped cream. Yield: 12-15 servings.
