how to run executable without terminal?

I have not tried this myself but I believe that you can run the program by:
1) Opening "Applications"
2) Entering the command in the searchbox
3) Press enter to run

Have you tried making it executable by typing the following?

chmod +x ./program

If that alone does not work you might want to create a program.desktop file (plain text file but with the .desktop extension). Here is an example how that has to look: https://wiki.archlinux.org/index.php/Desktop_entries#File_example Most important bit for you is the Exec= field where you probably have to put in the absolute path to your program, e.g. Exec=/home/marek/Desktop/program (unless your program is in certain directories, called $PATH).

didnt help ...

i created program.desktop file with this

[Desktop Entry]
Type=Application # Indicates the type as listed above
Version=1.0 # The version of the desktop entry specification to which this file complies
Name=jMemorize # The name of the application
Comment=Flash card based learning tool # A comment which can/will be used as a tooltip
Exec=/home/marek/Programming/project1/program # The executable of the application.
Icon=jmemorize # The name of the icon that will be used to display this entry
Terminal=false # Describes whether this application needs to be run in a terminal or not
Categories=Education;Languages;Java; # Describes the categories in which this entry should be shown
