Yes, there are several ways to do it. FLW is basically a filter that white-balances white flourescent lighting to daylight film. So, if you want to "nip it at the bud" while taking a picture and you don't have an FLW filter, then set the camera white balance to "Flourescent". It may not be exactly the same as FLW but it'll be close.
If you want to do it after the fact and you shoot in raw, set the WB to flourescent during raw conversion.
But if you have to do it in PS, then I can think of two options: 1) Use the "Color Balance" adjustment tool under Images or Layers, or 2) use the "Photo Filters" tool, also under Images or Layers.
Since I'm not sure exactly what color cast the FLW filter has (although it's probably has a some magenta in it), I can't give you the exact settings to emulate the FLW. But you should be able to play with the settings and tweak it so that the image comes out the way you want.
Just so your expectations are not set too high, you should know that that awesome skyline picture of Persian-Rice was not entirely due to the FLW filter although it did play a role in the colors that came out of it. There was a lot of Persian-Rice's photographic skills involved in getting the picture he did.
