How to install a .tar.gz program without using terminal?

[Valtam]

FYI, I did the following and it worked.

- Downloaded supertuxkart-0.9-linux.tar.xz to /home/jerry/Downloads
- Double clicked on the archive and extracted it to Downloads
- leafpad ~/Downloads/supertuxkart-0.9-linux/data/supertuxkart.desktop

my supertuxkart.desktop:

Code:

[Desktop Entry]
Name=SuperTuxKart
Icon=/home/jerry/Downloads/supertuxkart-0.9-linux/run_game.sh
GenericName=A kart racing game
GenericName[de]=Ein Kart-Rennspiel
GenericName[fr]=Un jeu de karting
GenericName[gl]=Xogo de carreiras con karts
GenericName[pl]=Wyścigi gokartów
GenericName[ro]=Un joc de curse cu carturi
Exec=/home/jerry/Downloads/supertuxkart-0.9-linux/run_game.sh
Terminal=false
StartupNotify=false
Type=Application
Categories=Game;ArcadeGame;

- mv ~/Downloads/supertuxkart-0.9-linux/data/supertuxkart.desktop ~/.local/share/applications/

It's in the Menu under Games.

Runs fine, no probs
