Preheat oven to 350°. Cream butter, sugar, egg, vanilla and lemon extract. Combine flour, baking powder, baking soda and salt; add to creamed mixture. Beat well, cover and chill for 30 minutes. Press this dough into a greased 12 or 14 inch pizza pan. Bake for 12 to 14 minutes and cool. Beat cream cheese and powdered sugar. Add Cool Whip; mix well and spread over crust. Arrange fruit; rings of strawberries, kiwi, oranges, bananas and place blueberries in open areas. Combine the sugar, orange juice, water and corn starch. Bring to a boil, stirring. Boil for 2 minutes. Cool to room temperature (30 minutes) and brush over fruit.
NOTE: This takes time, but is easy and worth making!
