Welcome to the forum! Now, for a bourke, the only good companion would be another bourke because they are an aviary species. As to a GCC, if you don't have hours and hours and hours to spend with a single bird, then I am afraid that a GCC is not the bird for you UNLESS you get two because GCCs are almost as needy of company as a cockatoo. You also mentioned a cockatiel or a budgie but I am afraid that they are also from aviary species so, again, they need to be kept in pairs for a happy and healthy life (only companion species do well on their own with a human and that only if the human spends many hours with them).
Now, it is possible for birds of different species to bond to each other but the thing is that you can't really predict with any degree of accuracy if this will happen... Let me put it this way: if you get a male and female of the same species, if it's aviary, they will always bond. If they are companion, it depends on the species, the age, the background and the expertise of the owner in getting them to bond. So, on a scale of 1 to 10, a male/female aviary species is a 10 while two unsexed birds of different large companion species are a 1, two similar species (like conures or amazons, for example) are 8 to 10. It all depends on the species, the gender and the human knowledge.
