It is possible. You need to separate the tasks, and the protocols will be different, so you need a microcontroller or similar to talk to the GSM module and the radio module.
There are three ways that I know of to communicate through a GSM modem.
1) By text message. This is the simplest, but potentially the most expensive. You can easily send a text to the GSM modem
2) GPRS internet connection. This needs some server that the GSM modem will connect to, although that could be just an email account. The problem with that method is that the GSM modem needs to initiate communication. That might be just checking for new emails, or asking again for a web page to see if anything has changed.
3) GPRS persistant connection.
https://en.wikipedia.org/wiki/Persistent_connection I don't have any direct experience of that, but a persistant connection allows the GSM modem to open a connection to a server, and then the server can send data at any time. That needs the server to be configured to use that connection.
Whatever you use, your microcontroller will receive the information and then send it out by radio. With radio modules, they are point-to-point communication and although you need to decide on a protocol, as long as the receivers are turned on, they can receive information.
The return journey is the reverse, but of course the GSM module can send the data to a server, possibly by email, and there is no problem worrying about leaving connections open.
