Your three primary options would be:
-Bucks County
-Lehigh Valley
-Monroe County
Bucks County is an affluent suburban area to the north of Philly that is still within two hours of NYC. There are a lot of quaint small towns and rural equestrian areas here, but urban sprawl is beginning to crop up via new housing developments, which you'll find to be attractive.

I'm pretty sure there is train service linking Bucks County to NYC, as there seems to be a growing number of NYC commuters moving to this county. Best of all is that Philly is also only 40 or so minutes away from most points in the county.
The Lehigh Valley may soon become the "Silicon Valley of PA" as Wall Street West continues to push its way into the PA frontier. Consisting of Lehigh County (Allentown) and Northampton County (Bethlehem/Easton), both counties offer a blend of suburban and urban living options. A popular community replete with newer housing developments is Palmer Township, as well as the townships that comprise the Saucon Valley School District. A number of people now commute to either Philly or NYC from the Lehigh Valley, so traffic congestion on Route 22 and I-78 can be heinous, especially at rush-hour. All three core cities have been in decline for decades and are in various stages of renewal. Bethlehem is getting back onto its feet much more quickly than its other two neighbors and is the most charming of the three cities, in my opinion. Easton is the next one in line to experience renewal, as it borders NJ, and Allentown, the third-largest city in PA, still has a ways to go.
Monroe County is what most people think about when they hear the word "Pocono." The county added 27,000 new residents in the past several years, and that growth is expected to continue to pick up steam as more and more NYC/NJ ex-patriates move here in search of a lower cost-of-living and more elbow room. The county used to be rural, but it is now transitioning to becoming a bedroom community to NJ/NYC, especially the areas closest to Stroudsburg, where new "big box" stores are being added to accomodate the growth.
A fourth option would be the Scranton/Wilkes-Barre area, which I think offers better suburban living options for you and your husband, but IT-related employment options around here are scarce, as the economy has been lagging behind the rest of Eastern PA for decades.
Best of luck!
