No, there is no software that will allow you to write bilingual in simultaneous fashion. Translation software doesn't translate in real time, and even when it does, it is usually grammatically unreliable because translating words and sentences between different languages that use different sentence structures (S-V-C vs. S-C-V for instance) can create errors when sentences don't directly translate.
This is why the process is to write a novel, edit it, proofread it, and then start translating it once it is adequately up-to-par in quality both structurally and grammatically.
