Linux Wi-Fi software connection

There are several questions regarding this functionality for Android or iOS, but I'm trying to do it on Linux (in particular for OpenWrt 15.05). I want to scan wireless networks, present the list to the user, select them and send username / password to the network.

I wrote a quick C program using iw_scan from the wireless_tools package, so I can see the wireless networks, but I'm having trouble trying to figure out how to connect to the wireless network. iwconfig from the same package is simply trying to modify an existing connection.

I spent several hours browsing the web and there should be a package that already does this, as this is such a common use case. Does anyone know one thing?

Thanks.
