The trouble with probabilistic programming is it requires very unnatural control flow to run inference on the models. Now there any solutions like Factorie, Figaro and Infer.NET where they are just a library you call into your code. The trouble is because of the representation you end up with much more verbose code. The cost of learning a new language isn't one you can avoid even if it weren't a language. To write these programs in any system you have to get used to thinking of your data as generated by this unobserved process. Thinking in that way isn't something you can avoid and is actually the main stumbling block.
