Thanks for the help.

Fantastic!
I'll have a great time trying them out!
Thanks!

There is currently no 'clear choice' for GUI in go. It will depend on you

In addition to Jake's question regarding whether you want to round up or
down I'll point out there isn't any to cast to float64 and back to int64.
If you want to "round down" just divide by four. If you want to "round up"
add one less than the divisor before dividing; e.g., bet := (cash + 3) /
4.
There is probably a better way, but lets start with a clear definition of
the problem. Your post says you want to "round *down*" but the variable
'bet' is the result of a divide by 4, rounded *up*. Which do you actually
want to do?

Yes, you can use go-astilectron. (electron + go)

I have written my first little piece of Go-code.
However it took some time and code for me to divide a int64 by 4 and round
down.
How can the last two lines be rewritten?

package main
import (
"fmt"
"bufio"
"math"
)
var cash int64
scanner := bufio.NewScanner(os.Stdin)
Thanks!
I see your point. I guess that is the main reason the type parameters
mapping needs to be in the same declaration line.
Still, for generic types it is ok, but for generic functions it feels a bit
too much stuff crammed into the signature line.
Thanks again for explaining!

Is there a gui library for Go, like Gtk+ or similar, which will produce a
statically linked executable ?
The aim is to create apps which do not require the user to install GTK or
any extra libraries in order to use the app.

There are two major issues with Go error handling:
1. It is not strict enough, i.e. the compiler cannot ensure error check
2. It is not consistent enough.
In the first you can easily ignore an error and the compiler will let you
go further. In the second, you can both
