SSH tunneling is so hard

Made MySQL program in python and it works with my windows laptop. I use putty to make the SSH-tunnel. But on my r-pi with linux i need to write stuff like:

ssh -fNg -L 3306:xxxxxxxxx.mysql.binero.se:xxxxxxxx@ssh.binero.se

And it makes me so confused. I managed to understand a lot but I think I have to learn a lot more before I get this to work... Going to continue with it tomorrow anyhow. Maybe I'll post on stack overflow for this one.
