This should work with Wifi. Untested and there are some warnings on build, but is built upon the working codebase for EMW3162 and the platform files from MXCHIP and WICED from Broadcom.
Nb. This is not from or endorsed by MXCHIP.
This is not an IDE, but it can be used with many free IDEs and WICED comes with an IDE for Windows.

I haven't tested it on my board yet, but it at least compiles and probably doesn't need much modification to work, if it doesn't already..
