Need guidance on which tool is suitable to build an app/website whichever takes less time [closed]

I’m not a coder, but a management student. I have opted for a course Agile Software Development Methodology. Now Working on a college project to create a library book borrowing app/website(hosted or local server). I have a fixed list of users and books stored in Google Sheets.

Goal:
User Authentication: Users should log in using their roll number.
Book Inventory: The app should display a list of available books and their status (available/issued).
Book Borrowing Request: Users can select books and send a borrowing request(by clicking “send request button”) to the library via email.

Constraints:
Time: I have a tight deadline of 2-3 weeks.
Technical Expertise: I’m a beginner with limited to no coding experience.

What I have tried so far:
I have asked ChatGPT to help me with Google Sheets and MIT App Inventor, but somehow the .js code which was shared by GPT to link Google Sheets API to MIT App doesn’t work hence the app stands unusable.

Request:
I’m looking for guidance on the most efficient way to develop this app/website within the given constraints. I’m open to using no-code or low-code platforms to speed up the development process.

Specific Questions:

  1. Recommended No-Code/Low-Code Platforms: Which platforms are suitable for this project?
  2. Data Integration: How can I integrate Excel/Google Sheets data into the app?
  3. User Interface Design: What are the best practices for designing a user-friendly interface?
  4. Email Integration: How can I implement email functionality to send borrowing requests to the librarian?

Any advice and code snippets/cloud platforms/or anything else would be greatly appreciated. Please help.
