How to save and use a trained model in an external application?

I have been using WEKA to train a RandomForest model for a binary classification system. I've been using CV to evaluate my model and now I achieve 96% classification accuracy on our supervised data with good generalization.

I want to now save the model and use it to classify in a separate program, potentially as a plug in for Chrome. I am not tied to WEKA. Does any one have experience with this, or suggestions?

Thanks
