I agree with the other post and suggest a Raspberry Pi.  That is probably
the quickest solution.

Another possibility is FreeRTOS. There are ports to many different MCUs
and various dev boards.  There is a lwip port and examples of web servers,
flash file systems and more.  I have used FreeRTOS on a NXP M3 and micro
ip (uip) tcp/ip stack.  I have not used lwip but there is active support
and discussion groups.
