I assume your data is in points , if yes then Instead of using SLD to create circles why dont you simply calculate or create a shape file and add geometries along with attribute data. It will suit you in the long term, since user might need to interact with the shapes and you cannot interact with an SLD label, and you will also have to update a single sld .thats how I would have done it
