Is it possible to load PNG Textures and draw Strings in LWJGL WITHOUT using the Slick Framework?

Everytime I google "how to load png images in lwjgl" I get answers like this -> "hey just use the textureloader from the slick framework".
Same for "how to draw strings in lwjgl" -> "just use the TTFFont Class from the slick framework"

But I don't want to use this half-way-crossframework design. Because I don't think that this is the best way.

Are there any Libraries or Extensions for LWJGL that are only made for Textures or Strings?

java image lwjgl
