Because CWM does not support your phone model, I assume you should search for an alternative recovery (TWRP, Philz).
Most installing methods require something like
fastboot or simply flashing an image to your phone, which is hard without a PC (Mobile ODIN may do the job, but I don't know about supported phone's).
For custom ROMs search xda-developers for your phone and that particular model in the appropriate subforum (look out for Android Development). There should be tutorials on how to install ROMs, recoveries, kernels etc., too.
