Why the heck not? You want it to be harder than it has to be? JHC, I swear there are so many hard to please people on this forum, it is ridiculous. If you have problems like this and weird requirements like you don't want to use iTunes, why dont you just take them to Google and stop wasting everyone's time here?
If you think iTunes is too difficult to use, then you definately wouldn't want to use Xcode. Xcode is a 2 gig download from the app store and requires a bit of technical knowledge to use.
While iTunes won't help you with deleting, figuring out what crashed and when is a no-brainer, as the log filename contains the date and time, like "LowMemory-2012-03-31-080530.log" or "Messages-2012-02-12-083317.crash".
