Ajax tabs for configurable product with description of child products

[Herecomes]

I need to create custom tab in configurable product, that will check, is there a description in child product, that is selected now and load description of child product. So for example in configurable product i select color: Red, after this, it should check, does this child product have description, if yes, load custom tab with description. Any suggestions even extension would be nice, thank you.
