Add radio button options to product

[Ice Cool Systems]

Basically what im looking for is a custom field that allows me to have radio/checkbox buttons on a given product.
These radio/checkbox buttons must add an extra cost to the total price as they are extras to the product.

I attempted to read the custom field sticky but that was of no use to me.

Any help is greatly appreciated
