It looked enough like a bean for us to let it grow and hope for
something useful.
However it is producing what look like seeds.
Any idea what it is?

It's hard to tell from the pics but is there any chance it's a Catalpa
bignoides?

I wouldn't have expected a Catalpa to flower at that size. Apart from
that Catalpa fruits are long pods, and its flowers are zygomorphic and
sympetalous (bilaterally symmetric with fused petals); while the picture
isn't clear, this plant under question appears to have actinomorphic
choripetalous flowers (radially symmetric with unfused petals)
