Can White win this?

Tantale, you don't have a GUI and a chess engine?

Analysis by Houdini after I let it look at the position for a few minutes:

21 [+8.27]  1. Bf7+ Kb5 2. d8=Q Qxg1+ 3. Kb2 Qc1+ 4. Kxc1 g1=Q+ 5. Kb2 Qh2+ 6. Kb3 Qh3+ 7. Ka2 Qh2+ 8. Ka3 Qh3+ 9. Bb3 Qc3 10. Qd5+ Kb6 11. Bd8+ Ka7 12. Qa5+ Qxa5+ 13. Bxa5 Kb7 14. Bd5+ Kc8 15. Kb4 Kd7 16. Kc5 Ke7 17. Kxd4 Kf6 18. Be4 Ke6 19. Bd2 Kd6 20. Bd5 Kd7 21. Bf4 Ke7 22. Bg5+ Kd6 23. Be3 Ke7 24. Ke5 Kd7  (288.48)

So yes, this position is won for White.  White has an overwhelming advantage.

Analysis by Stockfish (120727):

26 [+80.83]  1. Bf7+ Kc3 2. Be1+ Kd3 3. Bg6+ Kc4 4. d8=Q Qxg1 5. Kc2 Qf1 6. Qc7+ Kb5 7. Bd3+ Qxd3+ 8. Kxd3 g1=N 9. Qc4+ Kb6 10. Qxd4+ Kb7 11. Qxg1  (75.17)

I suspect tantale's questions are designed to get a discussion going, he already knows the answer

@MrEdCollins

And if I play 3...Ke2

After 1. Bf7+ Kc3 2. Be1+ Kd3 3. Bg6+ Ke2 then Stockfish gives the following: 

31 [+83.18]  4. Bh5+ Qxh5 5. d8=Q Qc5+ 6. Kb2 Qb5+ 7. Ka3 Qa6+ 8. Kb4 Qb7+  (78.78)

Ok you play 4.Bh5 I play 4...Kd3 you play 5.d8=Q, I play 5...Qxg1, you play 6.Qa5, I play 6...Qe3+ you play 7.Kd1, I play 7...g1=Q so we have the postion :

How do you win? I have two Queens!

You will need a GUI.  I recommend Scid vs. PC or WinBoard, but others like Arena, Tarrasch, Kvetka, etc.

From that position, I have a forced mate in 4 beginning with Qf5+

8 [M4]  8. Qf5+ Qe4 9. Be2+ Ke3 10. Qf2+ Qxf2 11. Bd2#  (0.00)

You mate me !!

The mate is :

Nice! Thanks!

Yes, this all has seemed a bit leading...

And people just plug it into their engine of choice to respond... an odd question and answer where neither party is invested in the matter at hand heh.
