Did you just admit to using Eclipse on this site?

Seriously, though, git-svn is very low on user interface, so you should be able to take the standard git plugin:

http://git.or.cz/gitwiki/EclipsePlugin

and use that for most of your work. When you want to get changes from svn, or commit changes to svn, just open up an xterm and type "git svn rebase" or "git svn dcommit". You may even be able to get Eclipse to run an arbitrary shell command for you, if so, you're set.
