Is this Possible...connecting two WAPs?

I have two small network I want to connect wirelessly to each other.

Can I do this without putting a 802.11 adapter on each computer on the 2nd
net?

Here are the details...

Net 1
Dlink Wireless router, connected to cable modem, 3 PCs connected directly to
router.

Net 2
Two PCs and a NAS connected through a linksys hub.
The PCs each have a 802.11 adapter but the NAS doesnt (no place to plug it
in).

PCs on Net 1 cannot see the NAS.

If I replaced the hub with a Wireless router could I get it connected to the
Dlink router that and would that enable the PCs on Net 1 to see the NAS?

Any other ideas would be appreciated as well

Thanks.
