We asked ATC for a clearance to deviate around WX. We were told we could deviate; go to ZZZ when able. First officer is PF. I called the flight attendants to tell them to take a seat and while I was talking to them; the first officer starts a turn towards WX. I come back up to try and find out what's going on. ATC had given him a heading which would take us through the WX. I called ATC to tell them we were unable to fly that heading due to WX. ATC says we need to do a 180 degree turn back out. We were between 2 lines of WX so we could not safely make the turn; which I told ATC. ATC said they would 'treat us as an emergency aircraft; squawk 7700;' so I did. We were told by ATC we had gone into restr airspace. Once clear of the WX; we were cleared back on course. I feel we handled this as best we could considering our first clearance to deviate around the WX. We had no idea restr airspace was ahead.

Title: B737 WITH CENTER AT FL220 ENCOUNTERED WX; ATC DECLARED EMER FOR ACFT AS IT ENTERED RESTRICTED AIRSPACE BECAUSE OF TURN LIMITATIONS.
Narrative: WE ASKED ATC FOR A CLRNC TO DEVIATE AROUND WX. WE WERE TOLD WE COULD DEVIATE; GO TO ZZZ WHEN ABLE. FO IS PF. I CALLED THE FLT ATTENDANTS TO TELL THEM TO TAKE A SEAT AND WHILE I WAS TALKING TO THEM; THE FO STARTS A TURN TOWARDS WX. I COME BACK UP TO TRY AND FIND OUT WHAT'S GOING ON. ATC HAD GIVEN HIM A HDG WHICH WOULD TAKE US THROUGH THE WX. I CALLED ATC TO TELL THEM WE WERE UNABLE TO FLY THAT HDG DUE TO WX. ATC SAYS WE NEED TO DO A 180 DEG TURN BACK OUT. WE WERE BTWN 2 LINES OF WX SO WE COULD NOT SAFELY MAKE THE TURN; WHICH I TOLD ATC. ATC SAID THEY WOULD 'TREAT US AS AN EMER ACFT; SQUAWK 7700;' SO I DID. WE WERE TOLD BY ATC WE HAD GONE INTO RESTR AIRSPACE. ONCE CLR OF THE WX; WE WERE CLRED BACK ON COURSE. I FEEL WE HANDLED THIS AS BEST WE COULD CONSIDERING OUR FIRST CLRNC TO DEVIATE AROUND THE WX. WE HAD NO IDEA RESTR AIRSPACE WAS AHEAD.
