Another hint:

#lang scheme

sets the language of the module you are writing. Good.

Now, if you want to include some libraries, you can do that:

(require net/url)

would load the "url" library in the "net" collection into your module.
Likewise, you can load the GUI stuff in as well.

(require mred/mred)

At that point, I think you can write things like

(define f (new frame% (label "Hi")))
(send f show #t)

and get an empty frame on the screen.

So, if you've been reading about namespaces, go ahead and relax: it
doesn't require that level of complexity so soon! Really, your module
language is likely to be "scheme" or "scheme/base", and from there,
you can require in the pieces that you need. Or, as has been
mentioned, you can use some of the other language combos (eg.
scheme/gui) which, I imagine, is effectively the same as requiring in
the appropriate libraries.

I'd also follow the advice of the previous posters about the
documentation, how to search it reliably, and so on.

Cheers,
