from the following link, DTEXEC.EXE looks like a good candidate. you could put the execution string in a batch file that the user could double click to run.

Can you put the scripts into the ssis package? if not you could also run the scripts (probably easier to put them into stored procedures) using SQLCMD via the same batch file (or a different one if that's what you need.)
