A very simple way is shown in the IDL help for h5_create.

simpleVariable = dblarr(10)
nels = n_elements(simpleVariable)
type = 'Double'
attr = {_TYPE:'Attribute', _DATA:{size: nels, type: type}}
dataset = {_Name: 'simpleVariable', _TYPE:'Dataset',
_DATA:simpleVariable, PROPERTIES:attr}
h5_create, dialog_pickfile(), dataset

If you know what you want your hdf5 structure to look like then it
becomes pretty simple to basically
build your IDL structure to look exactly the same way.

Not entirely sure if you were looking for something else but it's an
answer none-the-less
