Google Forms help and customization

so the idea is i will have a google sheet that will have a few columns, date, searchterm, approval, comment, userid. I will send a link to an employee and they will have a login to this form and when they will out a form the data will be inserted into the database. They will get a message before insert saying, "are you sure you wish to insert this record, once done it cannot be changed without contacting the admin". there might be more fields im not sure. Basically each employee that I assign permissions to will be entering the searchterm and approval code which will be a formatted as 123.45. They must be logged because i need records of each record an employee inserts but they cant access the google sheet main data.

If you also have technical abilities to create web applications and you do a good job I will be able to give you more work right away. I have experience in classic ASP and asp.net from a long time ago so recommendations of a used language I can understand and work with that is largely used.

The form would need to be complete in 48 hours maximum and ill work with you throughout to speed up the process.
