Is there any GUI available for patch command? I need it because sometime I need to see the actual file before applying patch to it and it is very cumbersome to open patch file and then open the individual files listed in there. Even if I do that I cant compare the modified i.e patched file and unmodified/unpatched file.

When you open a patch file in emacs, you can put the cursor on a hunk and hit
C-c C-cto jump to the corresponding location in the patched file and it will tell you if the patch has already been applied or not. Then you can useC-c C-ato apply the hunk.
