It's really not that hard, y'know.

Simple script to make a person say something:

loadpointer 0 (some offset) callstd 4 end

Where "some offset" is a regular GBA pointer, pointing to a line of text. This compiles to the following byte stream:

0F (that offset), 09 04, 02

Pokémon scripting is not that complicated.

As for applications to do it with, I haven't exactly kept track. Push comes to shove, you can always do it by hand in a hex editor. I have a list of commands and their parameters if you want.

Edit: added command delimiters to the byte stream. Also note that different applications may have different command names. The script editor that comes with EliteMap is sorely outdated and has missing commands. Missing commands mess up the code, parsing parameters as more commands.

Warps are funky, I for one haven't figured them out completely yet. All I know is that there are several variants, and all but one of these take three bytes and two variables as parameters.

warp (25, 24, 255, 0x6, 0x8);

^ Actual statement from Ruby.

That's one interesting thing you should know: a lot of commands take parameters that are either variables or integer constants depending on the value being higher than 0x4000. So you could either set a variable to 25 and pass that var to givepokemon, or you could call it with parameter 25 directly.
