A built-in standard mechanism for displaying information to users is page layout.
You don't need any programming knowledge to utilise the Page layout editor; all you have to do is drag and drop.
You must use a page layout if you need a simple form that only displays field values and related records.
However, if you want to use JavaScript, special HTML tags, or CSS on your page, you'll need to use VisulaForce pages, which are similar to JSF or other related technologies.
It's also worth noting that VisualForce can be used within normal page layouts.
Hope it helps!
