Caveat emptor... I don't know WxRuby at all. However, the
documentation (http://wxruby.rubyforge.org/doc/controlwithitems.html#ControlWithItems_append)
mentions a method:

Integer append(String item, Object clientData)

Parameters:
item - String to add.
clientData - Client data to associate with the item.

and a corresponding:

Object get_item_data(Integer n)

Parameters:
n - The zero-based position of the item.

So would this work?

@choice = Wx::Choice.new
Fruit.find(:all).each {|fruit| @choice.append(fruit, fruit.id)}

selected_fruit_id = @choice.get_item_data(@choice.get_selection)
fred = Person.create(:name => "Fred", :fruit_id => selected_fruit_id)
