Yep. I've been working with .NET since...
Saturday!

So this is all new to me, but I'm getting there.
Here it is:
Again, kept to see development, but the newest is further down in this post.

There are a lot of changes, all for the better. It looks much neater now, there's an about option, all the previous options are under "File" and there's syntax highlighting on the word "test." (I know it's not the right word, but it's a start)

I need to fix some of the syntax highlighting, make it start from the beginning of the current line as opposed to the beginning of the text every time, which will hopefully reduce the flashing.
Again, feedback is welcomed
EDIT:Here's the latest version. There's some basic C++ syntax highlighting going on, it doesn't highlight it when you load a file yet, but it does it as you type. It scans the text for the current line, so flashing is reduced.
Note that the cursor moves to the end if you type somewhere in the middle of the box at the moment. That's one of the next things that I'll fix

<edit> Newer version available
here </edit>
Here's a screen shot of the syntax highlighting in action:

I think the next addition will be preprocessor stuff, which makes the whole line a certain colour if there's a '#' at the beginning of the line.
Also, I'll make that stuff bold too, to make it stand out more.
