EDIT: You're also using invTweaks for 1.2.4 and MAtmos for 1.1..... Even if you were using the right BTW version, you would never get that setup to run. I would suggest looking at the versions before downloading and installing. Otherwise, reading the OP becomes somewhat pointless.
No none of them use forge. Otherwise his problem would have to do with missing a forge specific method or class
some mods in his list have just slapped a 1.2.5 sticker on their 1.2.4 mods though....
