If you are not too familiar with adb commands but still want to be able to push and pull files from your Android device, you might want to take a look at XDA forum member 7ymekk's application, Android Manager.

Android Manager is a window application based on adb (android debug bridge), which allows you to copy and remove files between your computer and Android device.

7ymekk has released a version of Android Manager for Linux and one for Windows, both written in C++.

Requires the Android SDK to be installed on your computer and busybox on your Android device.  Linux version requires Qt (framework) libraries to be installed.

You can find more information on the application thread.
