In reality, this game is actually far too easy to require the use of a trainer against the AI's and is considered to be poor gamesmanship and unfair to use one in online play against another person. All you need to do is start off against a single easy AI with all of the speeds turned down and the resource and research rates rates turned up and learn how to play the game. When you consistently beat that AI, either add in another AI or up the previous one's difficulty. Wash rinse repeat, while changing the speeds to something you're comfortable with. Eventually you'll have enough practice in that the AI's will no longer give you the feeling you're being challenged and that's when you should switch to online play against real humans who can think tactically and adapt strategies to combat you.
That being said, there are ways to get what you want.
The easy way:
Dev.exe
Control+shift+. activates the command menu. Essentially you're doing the command Control+> to open it up.
Pressing A twice get's you something like 10 million resources, instabuilds, no antimatter costs, no build limits for ships or structures, and all researches completed. Pressing the comma button twice exits the menus. You still have to build those 8 of each research stations to take advantage of all of the research, but when you can build all 16 in your home gravity well and build a dozen rapid fire super weapons, and fill up the rest of the space in that gravity well with trade ports, refineries, comm centers, hanger defenses, repair stations, etc... Really, that's the only planet you'll ever need, though you could take over a second one to have another planet to trade with to give you a massive income. Winning is super easy and you're robbed of the feeling of accomplishment you get taking out another race without the use of help.
The harder, much much much much more time intensive and consuming, but more rewarding since you have precise control over everything way that mimics the way trainers work and can actually be better then a trainer is a memory editor capable of scanning a running process for floating point values. I'm just going to assume you don't want to do this option so I'm not going to explain it since if you want a trainer for this game, you really don't care for any type of a challenge at all and the dev.exe is what you're going to go with.
