In the Command Prompt write /nABAPDOCU and press enter you get a rich tutorial on ABAP.

The steps of creating an ALV.(trying to giving you a rough idea)

1) Geta all your data in the Internal Table.

2) Create Field Catalog.

3) buil up a layout for the ALV.

4) Display of ALV (for this purpose you have to use FM like REUSE_ALV_GRID_DISPLAY,REUSE_ALV_LIST_DISPLAY,etc)

Thanks and Regards.
