Yep, then white usually plays Bf4 and a London set-up since the bishop already has a cave to hide in on h2. Sometimes they follow up with c4 instead of c3 if they're feeling particularly frisky...

I personally think 1.d4 f5 2.Nf3 Nf6 3.h3 e6 4.g4 b6 is risky for black. Just a few months after this post Simon Williams was crushed by a lower rated player in this variation.

I also tried this out 2 weeks ago but got away with a scar although in the endposition I had an easy win.

1.d4 f5 2.Nf3 Nf6 3.h3 e6 (In the book 'Win with the Stonewall Dutch', 3....d5 what I tried out in a earlier game, is not well regarded due to 4.Bf4 e6 5.e3 with a small plus for white. This small plus for white isn't fully clear to me but I must admit that e6 is certainly more flexible than d5 so keeping white to guess longer.) 4.g4 b6?! (I think here 4...d5 or even maybe 4...Ne4 with similar ideas sounds more healthy. One example from my own practice went 4...d5 5.gxf5 exf5 6.Rg1 g6 7.c3 Bd6 8.Bh6 Qe7 9.Nbd2 Nbd7 10.e3 Ne4 11.Be2 Ndf6 and black has a comfortable position and went later on to win the game.) 5.Bf4?! (I don't think that you can see at this stage that the bishop belongs to this square. More to the point seems to me 5.gxf5 followed up by e.g. Qd3 or Rg1 which gives to my feeling some advantage for white) 5...Bb7 6.Nbd2 Nc6N (An improvement found on the board. Be7 and c5 which were tested earlier with miserable results look less good.) 7.Rg1 fxg4?! (Interesting idea but not the best. Better seems to me Qe7. C7 is poisoned due to d6 and bishop on f8 can go to g7 after g6 of course.) 8.hxg4 Bd6 9.Bxd6 cxd6 10.e3 Qe7 11.c3 0-0-0 12.Bb5 Nd5 13.Qa4 Kb8 14.0-0-0 Nc7 15.Be2 Rdf8 16.Qa3?! Rf7?! 17.Ne4?! Rhf8 18.Rg3 Nd8 19.Neg5 Nf6 20.e4 Rf4 21.e5 Ne8 22.exd6 Nxd6 23.Ne5 Rxf2 24.Nxh7 Rxe2?! 25.Ng6?? (Looked decisive but in fact blunders the position away. Nxf8 would be good enough for at least a small advantage) 25... Rc2+ 26.Kb1 Be4! 27.Nex7 Rd2+ 28.Kc1 Rc2+ 29.Kb1 Rd2+?? (Rxc3 is of course winning but with less than 20 seconds left I couldn't calculate it properly anymore so settled for a draw which was anyway more than enough for the teamvictory.) 30.Kc1 Rc2+ 31.Kb1 and draw.

Like to hear some comments on the opening from people whom have some expertise in it or possess the book 'Dangerous Weapons the Dutch' which treats these lines.

I guess Dutch types go 1..e6 to avoid the Staunton Gambit (2.e4) and the Bogoljubow Variation (2. Lg5). 

Maybe any Dutch experts could comment?

Every Dutch playing schoolboy knows that you always take the first gambit pawn and never the second.  Your d5 recommendation is one way of following this rule, and and leads to a position where Black has as many winning chances as White.
