There are some frontends available, but they all suck, are no longer maintained or are hard to install.
As a surprisingly comfortable alternative I have found a command line tool s3cmd:
sudo apt-get install s3cmd
When you run s3cmd the first time it will ask you for your access key ID and secret access key. This information is cached somewhere so you only need to write them once. To reconfigure later, call s3cmd --configure.
Once you're done setting up, s3cmd gives you shell-like commands like s3cmd ls or s3cmd del somefile.png.
Here is a full list of commands it understands:
Make bucket
s3cmd mb s3://BUCKET
Remove bucket
s3cmd rb s3://BUCKET

s3cmd ls [s3://BUCKET[/PREFIX]]
