Any of the entry level DSLR's would be fine. Canon or Nikon are both good - it depends on your preferences, or perhaps if someone you know owns the same brand.
The lenses are much more important, because they will stay with you even when you upgrade to a new camera body, so make sure to buy the best you possibly can when it comes to lens shopping - you WILL regret buying slow lenses. At least for starters, the kit lens that comes with the camera will do you fine (until you learn more about it all and come to know what else you need/want).
Canon tends to be a little cheaper and have a bit more choice, including on the second hand market.
Pick a favorite few cameras, compare them on www.dpreview.com, then play with them in a store...... handling them might help you decide which one to get.
The very best thing you can do for your photography, is to attend a class and read a few books and tutorials. Having some knowledge will make a huge difference to your images.
I hope I have expressed this idea clearly enough: YOU need to learn about photography because even the world's best camera will take lousy shots in the hands of someone who has no clue how to use it.
