You'll have to use the preexec function -- which means it'll work only at
the command line, only at the PS1 prompt (not inside a function body or a
loop body or a subshell or ...), and only in zsh 4.0. [*]

    function preexec {
	local cmd
	cmd=(${(Q)${(z)3}})
        # Adjust this URL recognition test as necessary
	if [[ $cmd[1] == (http://*|www.*.*) ]]; then
	    eval "function ${(q)cmd[1]} {
		unsetopt noglob
		w3m ${(q)cmd[1]}" '$*
		unfunction' "${(q)cmd[1]}
	    }"
	    setopt noglob
	fi
    }

You can probably do without the noglob twaddling; I put it there just so
you don't have to quote question marks and tildes (~) and so forth in the
URLs, but you still have to quote ampersands (&) and semicolons.

[*] Actually preexec is available as far back as 3.1.3, but the complete
combination of things in my example are available only as of very recently.
