I haven't come across a program that does this. But, here a bash
one-liner that does at least part of what you want. It should be one
big line, replace /dev/hda2 with your partition, run as root. Its
output is like:

/dev/hda2, 1024 byte/block, 16452 kb journal

part=/dev/hda2;blocksize=`tune2fs -l $part | awk '/Block size/ {print
$3}'`;tune2fs -l $part | awk '/Journal inode/ {print $3}'  | xargs -i
debugfs -R 'stat <{}>' $part 2>&1 | awk '/Blockcount/ {print $4}' |
xargs -i expr {} \* $blocksize / 1024 | xargs -i  echo $part,
$blocksize byte/block, {} kb journal

Use stat or ls -lu.
