In a large bowl toss together apples, pear, oranges, cranberries, grapes, and lemon juice. Set aside.
In a small bowl, whisk together butter and maple syrup. Use a microwave or double boiler to melt them together if the butter is solid. Stir in cinnamon and nutmeg. Add pecans and hazelnuts.
Drizzle the spiced butter mixture over the fruit while reserving the nuts in the bowl. Toss the fruit well with the spiced maple butter. Transfer the fruit to a baking dish and scatter with the reserved nuts on top. Bake for 1 hour.
Divide into serving bowls. Serve with ice cream on top.
