What is the correct way to completely remove an application?
Is it possible to undo an apt-get install command?

Most of the time when I want to try a new program, the package manager tells me that I also need to install certain dependencies. Figuring that the program will not work without these dependencies, I install all of them. Sometimes the program is good, other times the program doesn't work or crashes or I just don't like it.

How can I uninstall the program and all the dependencies that were installed with it?

Do I need to manually keep track of what gets installed when and where and what it needs to function?

I don't want a bunch of useless or otherwise unused programs cluttering up my computer, wasting space and slowing my system down. How can I get rid of it without guessing what I should and shouldn't need to keep?

Edited 2/4/2013 to differentiate question:

Is there any way to remove do this without resorting to the command line? I use Muon in kubuntu and Synaptic in lubuntu. Can neither one of these programs remove the software and dependancies that it installs?

If you are not a power user or developer who create programs, dependency tracker is there to mark the obsolete package.

Just run

sudo apt-get autoremove to remove unused dependency.

Also if you want to clean the downloaded cache files (installers at /var/cache/apt/archives that are used for installation you can run

sudo apt-get clean
