There is a frequency dictionary you could use. but...

Have you tried my videos: https://www.youtube.com/channel/UC2XoO1HBizGfvZR01kK_VJQ/playlists

more than 40 from 60 videos are already subtitled (always in German, most in English too, some in a lot of languages such as Russian, Chinese and Arabic). If just in German you should translate every word yourself (easy with google). You need to have an idea about what Im talking. This method works also for beginners from 0, I promise you, cause I did this with Russian, it works!
You should also take an axercise book (daftarun) and write every word, that you want to learn. In the beginning search for words like: I you, cold, warm, good bad big small, etc. So easy words. Cause for a small conversation we just need around 400 words in most languages :-), than you search for a language partner here on italki and start speaking, speaking speaking.
If there is one day you didnt learn yet: Learn at least 5 minutes before going to bed. You really should learn every day (better just a little than nothing) if you want to have a fast and easy progress

Just on top you can also listen to them for example while making a walk or something.
Feel free to tell me if you need a special topic! I shall talk about!!
I think it's the best method, cause me myself I learned that way and found it much easier than I've ever learned before.

Hope you'll succeed the fastest possible!
