How to create a working computer?

I was wondering on how to create a fully working computer? i've learned the following LUA things through Minecraft Tekkit Computercraft which has really helped but now i want to expand into Roblox

write("Password: ")
input = read("*")
if input == "password" then
 bunch of minecraft code stuff..
else
 print("Invalid Password!")

I know mostly the code only relevates to Minecraft but i felt it may help later down the road. So i was wondering how can i create a simple website GUI that allows 1 - Logo 2 - Navbar w/ clickable buttons 3 - Webpages of which users can submit with a easy Website Kit.

I've started my own (N-Net) 2 years ago but not knowing Lua stopped me majorly.

Basically, you can use SurfaceGuis on parts to create computers.

You can position TextButtons and such to create the Navbar and use an ImageButton to create the logo. You can then use the MouseButton1Down event to make certain frames visible/invisible to simulate loading a new page.

Try checking out some site layouts to find out some good ways to position your Guis.

Cant help there, I guess you would you function.true"Your image here" If so true. end. I dont know.
