There would still be tedium, entering all the dice rolls into the calculator, unless you want to take away the dice rolls for the DM, and have the computer roll them to autopopulate the simulation lookup.
(or sell some gimicky device that can tell what dice were rolled inside of a button-popper dice roller, that can feed data to the app.)
If I were going to do this, I would do it with the OPTION of allowing manual dice roll imputs, but with the preference of auto-dice roll simulation by the DM, coupled with some template hybrid material types with appropriate names: "Large oak chest with iron hinges", etc. It would then be up to the DM to make scenarios with appropriately chosen materials, or to derive appropriate materials for the computer to simulate.
The idea is to have the computer aspect be painfully easy to use-- Pick a scenario event by ID number (since you will have needed to supply it tables to do its simulations anyway), some optional meta flags (Like "Object thrown" instead of "Item smash") then press the CALCULATE button. It displays dice roll values for the event, and damage values given. With some polish, it can even give the "wear" on your weapons, if any.
For the "Video games" argument-- Not exactly. That COMPLETELY replaces the DM with a computer. You cannot give off the wall commands, and get the DM to translate that into workable inputs. Computers just cant do that yet. Instead, this would be a tool for the DM to help manage very complex simulations.
