A hexblade warlock is pretty close to this. Although the casting part is pretty limited in this instance, they can use the Hex spell and the Hexblade's Curse. They also have a few other spells that can be considered similar to curses. If you want more spell slots, you could always multiclass. As you can use spell lots from other classes to cast warlock spells and vice versa.
Another option is to use one of the fan-made classes from the DM's Guild or design your own. Personally one class I'd like to see become official is a Witch class (like the one I sorta started designing) which is sort of a cross between the sorcerer (spellcasting-style and magic origin) and the warlock (theme), but also has its own unique gimmick.

Warlock. You get hex and bestow curse,armor of Agathys and hellish rebuke can be phrased as curses, and if your DM has Xanathar's Guide to Everything, there are a bunch of Eldritch Invocations that have to do with curses and you can choose the Hexblade patron for Hexblade's Curse.

Personally, I would stay away from the warlock as a beginner, too many moving bits and a completely different understanding of spell slots. A sorcerer, a wizard or even a bard would be easier to play as a beginner.

For a beginner, I would go wizard. I agree sorcerer could do the job, but I don't think sorcery points would be as useful in this application. Wizard also gives a bit more variety in spells and spells known.
So, I am new to D&D and wanted to make a character that can use a lot of curses, which class would you recommend for such a character

Thank you all very much
The witch class is looking like a very fun class to play with

The warlock isn't as complicated as you think, if you just stick with Book, and ignore the other options.
Also, talk to the GM about Rod of the Pact Keeper, since that boosts your Save DCs, making it harder to ignore your curses.
thanks
